Public access to the Rocky Mountain Arsenal National Wildlife Refuge has increased greatly now that they allow visitors to drive their own vehicles through the facility. We have taken advantage of it over the past couple of weeks and have enjoyed some extraordinary photo opportunities.
A wide variety of birds are available for viewing but the hawks and eagles draw the most attention. These are readily seen throughout the refuge although the trees right near the entrance seem to be a very popular spot with them. We were able to get extraordinarily close to one bald eagle that didn’t seem to mind visitors at all.
Deer and of course prairie dogs abound at the arsenal and are easily spotted. Also routinely seen are coyotes but seeing them requires a keen eye as they blend in with the grass.
Up until this past week the refuge’s bison herd largely had remained out of sight. Most were in areas not accessible to the public and the few that were mostly stayed hidden. This week though the herd moved into the main area and on our recent visit we found them right on the road.
Below are some of the photos we have taken in recent weeks.
January 27 to February 2: This Week in Denver Weather History
High wind and heavy snow events dominate our look back at this week in Denver weather history. Most notable is a major snowstorm just last year that helped to provide at least some relief from tinder dry conditions. Hopefully we can see some of that this year!
From the National Weather Service:
25-27
In 1897…a cold spell resulted in three temperature records. Low temperature of 14 degrees below zero on the 27th was a record minimum for the date. High temperatures of only 3 degrees on the 25th and 2 degrees on the 26th were record low maximums for the dates. Very light snow or flurries fell on the 25th and 26th at times.
26-27
In 1944…heavy snowfall totaled 8.0 inches in downtown Denver. Most of the snow…7.0 inches…occurred on the 26th when northwest winds were sustained to 17 mph.
In 1973…at Stapleton International Airport…only 3.8 inches of snowfall were measured and north winds gusted to 40 mph causing some blowing snow…while over the Colorado eastern plains heavy snow accompanied by high winds created widespread blizzard conditions closing many highways.
In 1994…the combination of an upper level storm system and moist upslope winds brought heavy snow and cold temperatures to metro Denver and much of eastern Colorado. Snowfall across metro Denver averaged 5 to 7 inches. Snowfall totaled 3.8 inches at Stapleton International Airport where east winds gusted to 21 mph on the 26th.
In 2000…snow…heavy in the mountains…spread over the foothills and metro Denver. Eight inches of snow were measured at Bergen Park and near Evergreen. Snowfall totaled 3.8 inches at the site of the former Stapleton International Airport.
26-1
In 1888…a protracted warm spell lasted a week. Maximum temperatures ranged from 62 degrees on the 29th to an all-time record high for the month of 76 degrees on the 27th. Daily record high temperatures of 76…69…and 71 occurred on the 27th…28th…and 30th respectively. Record high minimum temperatures of 47 and 34 occurred on the 26th and 27th.
27
In 1888…the highest recorded temperature in January…76 degrees…occurred.
In 1967…strong winds caused a power outage in Boulder.
In 1984…this was the last day of 63 consecutive days with snow cover of one inch or more in Denver. This longest period of snow cover on record began with the Thanksgiving weekend blizzard on November 26-27…1983… When 21.5 inches of snow fell at Stapleton International Airport. Additional snowfall during December and January prolonged the event. Snow depth on the ground to the nearest inch was measured once daily at 5:00 am MST.
27-28
In 1899…snowfall totaled 6.2 inches in the city. Northeast winds were sustained to 36 mph with gusts to 40 mph on the 28th.
In 1965…high winds raked the Front Range foothills. West winds gusted to 89 mph on Table Mountain in Boulder…87 mph at Rocky Flats…and 54 mph at Stapleton International Airport. Damage and minor injuries occurred in Boulder and western metro Denver. Four men were injured by wind- caused accidents while working on construction…2 in Denver and 2 in Boulder. There was extensive damage to power lines… Buildings…signs…and trees. Some minor accidents were caused by blowing dust and debris. Blown dust accumulated 2 to 3 feet deep on some lawns in northern metro Denver suburbs. Dust blew into buildings and homes.
In 1989…the heaviest snowstorm of the winter dumped 9 to 15 inches of snow across metro Denver. Snowfall totaled 8.8 inches at Stapleton International Airport with most of the snow…8.6 inches…falling on the 28th. Strong north winds gusting to 46 mph whipped the snow into 2-foot drifts and reduced visibility in blowing snow. The foothills received up to 18 inches of snow. The snow fell on a weekend…so closures and other disruptions were minimal. The public reported thunder in Arvada…Wheat Ridge…and Boulder on the evening of the 27th. A thunderstorm produced snow pellets at Stapleton International Airport during the early morning hours of the 28th. This was the first thunderstorm in the city during January since 1932.
In 1996…winds to hurricane force were reported across the Front Range foothills in the wake of a pacific storm system. Recorded wind speeds included: 86 mph at the National Center for Atmospheric Research southwest of Boulder…86 mph atop Squaw Mountain west of Denver…and 75 mph at Jefferson County Airport in Broomfield. West-northwest winds gusted to 48 mph at Denver International Airport on the 28th.
In 2009…high winds buffeted the foothills of Boulder and Jefferson counties. Peak wind gusts included: 101 mph at Eldora Ski Resort…100 mph…6 miles northwest of Boulder; 84 mph at NCAR Mesa Lab…79 mph…5 miles northwest of Boulder; and 75 mph at the national wind technology center. In Nederland…a wind turbine recently installed was damaged by the high winds. A peak wind gust of 38 mph occurred at Denver International Airport on the 28th.
27-31
In 1951…a major storm dumped 10.1 inches of snowfall at Stapleton Airport. Most of the snow…8.3 inches…fell on the 29th. Cold arctic air accompanied the snow. Several temperature records were set…including record low maximum temperatures of 4 on the 28th and 4 below zero on the 29th and record low temperatures of 12 below zero on the 29th and 24 below zero on the 31st. Temperatures were below zero for 45 consecutive hours.
The 2012 / 2013 snow season has been dismal and while December brought some hope for recovery, recent weeks have seen snowpack decline once again. For the drought and fire weary state of Colorado the data does not bode well.
For the north-central Colorado mountains, the January 22 snowpack is at its second lowest level to date since 1979. Only 1981 saw worse results this far into the season.
According to the latest Colorado SNOTEL reports, the South Platte, North Platte and Upper Colorado River basins are at 57%, 65% and 60% of normal respectively. Statewide Colorado snowpack is a dismal 62% of average.
Is there hope? Mother Nature certainly works on her own schedule so it is possible we could see a recovery. However the latest 3-month outlook from the Climate Prediction Center forecasts warmer and drier than normal temperatures.

After taking the oath of office for his second term, President Barack Obama laid out his vision for the next four years and included a call to action to battle the ‘threat of climate change.’
Mid-way through his address the president said, “We, the people, still believe that our obligations as Americans are not just to ourselves, but to all posterity. We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations.” Read the rest of this story and watch video of Obama’s climate change commentary on Examiner.com.

President Barack Obama will be sworn in for his second term today and while the weather looks to cooperate for the ceremony on the steps of the Capitol, that hasn’t always been the case. Mother Nature has impacted previous Inauguration Days and most famously led to the death of a president. Read the rest of this story on Examiner.com

January 20 to January 26: This Week in Denver Weather History
Damaging wind events dominate our look back at this week in Denver weather history. Also making appearances are extreme cold and significant snowstorms.
14-21
In 1930…a protracted cold spell occurred when low temperatures plunged below zero on 8 consecutive days. The coldest low temperatures of 20 degrees below zero on the 17th and 19 degrees below zero on the 16th were record minimums for the dates. High temperatures during the period ranged from 18 on the 18th to zero on the 20th. Two degrees on the 15th was a record low maximum temperature for the date.
15-23
In 1962…a protracted cold spell kept metro Denver in the deep freeze for more than a week. From the 15th thru the 23rd…low temperatures were zero or below for 9 consecutive days…but a daily record low was set only on the 22nd when the temperature dipped to 14 degrees below zero. A record low maximum for the date was also set on the 22nd when the temperature climbed to only 11 degrees. The coldest high temperature was 3 degrees above zero on the 21st…which did not break the record. The protracted cold was broken for only a few hours on the afternoon of the 20th when Chinook winds warmed the temperature to a high of 38 degrees before another surge of cold arctic air plunged temperatures back into the deep freeze that evening. The severe cold caused much damage to water systems. A woman was frozen to death at Morrison. There were other deaths attributable to the weather…including traffic deaths and heart attacks from overexertion.
18-20
In 1958…snowfall totaled 6.9 inches at Stapleton Airport where east-northeast winds gusted to 26 mph on the 18th.
18-24
In 2005…a week of mid-winter unseasonably warm weather pushed high temperatures into the 60’s or more on all but one day. During the period…the highest temperature of 70 degrees on the 20th was a new record maximum for the date. Low temperatures remained above freezing on 4 of the days.
19-20
In 1935…snowfall of only 0.8 inch during the evening of the 19th was the only measurable snowfall of the month. The light snow developed behind an arctic cold front as temperatures plunged to a low of 13 degrees below zero on the 20th. High temperature of only 2 degrees on the 20th was a record low maximum for the date. Northeast winds were sustained to 16 mph on the 19th.
In 1986…Chinook winds gusting to 39 mph at Stapleton International Airport provided record breaking warmth. The warmest temperature of the month…68 degrees on the 19th…was also a record high for the date. The low temperature of 41 degrees on the 20th equaled the record high minimum for the date.
In 1991…a strong cold front moved south across metro Denver. Upslope conditions produced 3 to 6 inches of snow along the Front Range with 5 inches in Westminster and 4 inches in Thornton. Snowfall measured 4.9 inches at Stapleton International Airport where north winds gusted to 31 mph.
20
In 1894…northwest winds were sustained to 40 mph with gusts to 45 mph in the city.
In 1911…west Chinook winds sustained to 46 mph warmed the temperature to a high of 62 degrees.
In 1975…a warm Chinook wind produced a west wind gust to 53 mph at Stapleton International Airport. Winds were much stronger near the foothills…where 80 mph winds in Boulder caused damage to homes…buildings…power lines… And autos.
In 1986…high winds buffeted the foothills from Denver north. The strongest reported wind was 72 mph in Fort Collins. A wind gust to 39 mph was reported at Stapleton International Airport in Denver.
In 1996…high winds developed for a short time in the Front Range foothills in the wake of a weak upper level disturbance. Wondervu recorded a peak wind gust to 90 mph… While winds gusted to 84 mph atop squaw mountain near Idaho Springs. West winds gusted to only 29 mph at Denver International Airport.
In 2011…a snowboarder and his dog were killed when he triggered an avalanche in the backcountry northeast of Berthoud Pass.
20-21
In 1973…a major storm produced 7.5 inches of snowfall at Stapleton International Airport where north winds gusted to 32 mph causing some blowing snow.
In 2002…high winds developed over portions of the northern mountains and Front Range foothills. Several trees were blown down in Gilpin County along State Highways 119 and 46. Wind gust reports included: 90 mph 11 miles north of Central City…83 mph near Fritz Peak…76 mph at Aspen Springs…and 80 mph at Nederland. West winds gusted to only 39 mph at Denver International Airport on the 20th.
Disasters claimed thousands of lives in 2012 in the form of floods, earthquakes, tropical storms and tornadoes. This week NOAA released its list of top 10 global weather and climate events and natural disasters took their place in a number of spots. Drought in North America which we of course have seen here in Colorado makes the list as do many other notable disasters.
Following on the release of data showing the United States saw its hottest year on record, the nation’s agencies responsible for monitoring climate said this week that 2012 temperatures globally were similarly well above normal.
Using slightly different methodology, NASA and NOAA ranked global temperatures in 2012 as the 9th and 10th warmest on record respectively. The difference in ranking is considered irrelevant and has global warming alarmists touting the figures as proof of man’s impact on the Earth’s climate.

When a cold front pushed through Colorado late last week not only did it bring bitter cold temperatures, it also brought a great deal of wind to the state’s southeastern plains. NASA’s Aqua satellite was able to capture images of the ensuing dust storm as the cold front pushed through.
As wind speeds increased dust was thrown aloft in southeastern Colorado on Friday, January 11. The intensity of the dust storm was undoubtedly aided by the dry landscape in what is the most parched part of the state.
Satellite imagery captured the dust storm as it moved into Kansas.
NASA writes:
Although the dust was thickest in western Kansas, many of the source points for the storm were in Colorado. One dust plume arose roughly 70 kilometers (40 miles) south of Colorado Springs. In Kansas, the eastern edge of the dust storm spanned 240 kilometers (150 miles) and the dust was thick enough to completely hide the land surface below, especially east of Goodland. Salina.com reported that the blowing dust reduced visibility to a quarter of a mile (0.4 kilometers).

There was a time activity at the Rocky Mountain Arsenal was centered on our nation’s defense as a location responsible for manufacturing chemical and conventional weapons. Now a National Wildlife Refuge, the site is one of the hidden gems of the Colorado Front Range when it comes to wildlife viewing.
As the Cold War wound down, the government began to clean the site up. It was an expensive project but one that saw the contaminated site transform into one that must be seen.
Encompassing more than 15,000 acres, Rocky Mountain Arsenal National Wildlife Refuge is home to a wide variety of native animals, birds and reptiles. Deer, hawks, eagles and even buffalo are seen daily at the site in the heart of Denver.
A new visitor’s center opened at the refuge last year and now visitors can drive their own vehicles along nine miles of roads through the interior. In the past touring the facility required riding on a bus operated by the facility.
If you have never been, the Rocky Mountain Arsenal National Wildlife Refuge is a ‘must see’ for everyone.
