Boulder Open Space and Mountain Parks news
Jun 7th
Specifically:
• A report of a sinkhole forming in the middle of the Teller Trail. Collapsing edge was fenced off until repair could begin.
• A series of wildfires that occurred near Celestial Seasonings caused by a train creating sparks. A Ranger tied in with local crews to put out the string of small conflagrations.
• A mountain lion in a yard on a cache in the 700 block of Juniper. The lion was seen to have experienced some type of trauma. Rangers worked with CPW to tranquilize the cat in an attempt to relocate. The lion did not survive and upon examination had massive injuries consistent with a fight with another lion. Awaiting necropsy results.
• Rangers located a wanted subject camping along the S. Boulder Creek on the Van Vleet Property. His warrant was from Aurora for trespassing when he attempted to hitch a ride on a train.
• Another coyote attack on a dog. This one was on the Gunbarrel trail. RP was walking with 2 dogs one of which was attacked. The other dog attempted to help his buddy. No serious injuries.
• Injured hike in Bear Canyon. Twisted ankle. Rangers worked with AMR and Boulder Fire to evacuate the hiker from Mesa Trail at Bear Canyon.
•Two ill hikers at once. A Ranger assisted AMR and Boulder Fire evacuate an adult male who had overheated. The same ranger then assisted an 11 month old who had been hiking with his mother. No serious injuries.
•A Ranger happened upon an injured raccoon that needed to be put down.
•Rangers were called to an assault in progress on the Baseline Trail. A 67 year old male was photographing the Chautauqua meadow when an unknown subject approached him from the area of the Ski Jump Trail. The unknown subject had a 3 foot stick which he used to strike the victim on the left side of his head. The suspect struck the victim a second time but he was able to fend off that blow with his arm. The suspect then fled back up into the woods. A massive search was conducted by Rangers and the BCSO including a K-9. The suspect has not yet been located or identified. The victim did get 2 blurry photos of the suspect prior to being hit. Investigation on-going.
Towhee/Homestead
Seasonal employees have been in the area to remind people of these changes.
Outreach staff to hit the trails
As of the afternoon of 5/28/2013, the new regulations went into effect. We will be conducting outreach on the Towhee & Homestead trails. On Old Mesa we will not be conducting outreach, at least not now. We are going to break with tradition and have outreach staff hike the trails as we conduct outreach, rather than set up at the South Mesa Trailhead. The focus will be Towhee, as that’s the big change. Everything should be up to date as far as signs. Please keep me aware of contact numbers, public feedback & compliance. Here are the long awaited changes:
Towhee Trail: Will change to “NO DOGS”. There is a short section at the start of the Towhee trail that will remain voice and sight, until visitors come to the junction with the Homestead trail. That is where Towhee becomes “No Dogs”.
Homestead Trail: This trail will remain “Dogs must be under voice and sight control with a green voice and sight tag”, until you get to the bridge where it crosses the Towhee drainage. That small section (approx. 20 feet from either side of the bridge) will become “dogs must be leashed”.
If you have not been on this trail since the reroute, you should hike up there and take a look.
Old Mesa Trail: This trail (and surrounding drainage area) will now be “dogs must be leashed”, from the social trail just off the shadow canyon trail, down to our property line near Eldorado Springs. FYI there is no public access from the Eldorado Springs side as the trail leads you down to private property.
Visitors should consider this a down and back, not a destination trail.
We are now implementing regulations that were decided on during the West Trails Study Area planning process (WTSA) which included the Community Collaborative Group (CCG) which was an extended community input process. The input process began in 2009 was completed in 2011. Only recently have the regulations and signs been changed. If you would like to learn more about how that process worked, you can go to our website OSMP.org
The Towhee Trail’s new regulations help protect the riparian area it goes through. It is a heavily traveled wildlife corridor. The changes also provide a “no dog” experience for hikers. Most of the surrounding trails allow dogs.
The Homestead trail’s regulation change was made to protect the riparian area and sensitive vegetation through the Towhee drainage.
Trails news:
On Saturday, June 1st, we had 22 volunteers help construct the new trail re-route at Upper Big Bluestem as our National Trails Day project. (National Trails Day is a national trail volunteer event sponsored by the American Hiking Society.)
This year, OSMP volunteers constructed 240 feet of the new trail re-route, and installed a new pedestrian gate in the fence line. The weather was great; volunteers worked hard, and completed a lot of great work. It takes a small army to pull off these projects. Manythanks go to:
–Trails staff John Leither and Frances Boulding for project planning and logistics.
–Kristin Weinberger for promoting the project, recruiting volunteers, implementing day-of logistics (food, registration, etc), and arranging for great food from Black Cat!
–Trails crewmembers Sean Murphy, Beau Clark, Alex McClellan, and John Goepel for doing a great job of leading volunteers on crews!
–Jennelle Freeston and Lisa Dierauf for supporting project logistics and planning.
Boulder Mountain Bike Patrol is kicking off their trail work season by helping OSMP maintain the Springbrook Loop. The Bike Patrol worked on Prairie Vista Trail with us in 2011 and 2012, and is taking on a number of trail maintenance projects on Springbrook for 2013. Their goal is to do projects at least once a month, typically the last Thursday of the month during the evening hours. OSMP trails staff plan trail maintenance work, and meet up with the group to lead the project. On Thurs, May 30th, we had eight volunteers work with us for the first project of this year. They completed eight rolling drainage dips on Springbrook North to help shed water off of a roughly 500-foot section of trail that is experiencing moderate erosion issues.”

CU study: Melting glaciers are largely responsible for sea level rise
May 16th
The new research found that all glacial regions lost mass from 2003 to 2009, with the biggest ice losses occurring in Arctic Canada, Alaska, coastal Greenland, the southern Andes and the Himalayas. The glaciers outside of the Greenland and Antarctic sheets lost an average of roughly 260 billion metric tons of ice annually during the study period, causing the oceans to rise 0.03 inches, or about 0.7 millimeters per year.
The study compared traditional ground measurements to satellite data from NASA’s Ice, Cloud and Land Elevation Satellite, or ICESat, and the Gravity Recovery and Climate Experiment, or GRACE, missions to estimate ice loss for glaciers in all regions of the planet.
“For the first time, we’ve been able to very precisely constrain how much these glaciers as a whole are contributing to sea rise,” said geography Assistant Professor Alex Gardner of Clark University in Worcester, Mass., lead study author. “These smaller ice bodies are currently losing about as much mass as the ice sheets.”
A paper on the subject is being published in the May 17 issue of the journal Science.
“Because the global glacier ice mass is relatively small in comparison with the huge ice sheets covering Greenland and Antarctica, people tend to not worry about it,” said CU-Boulder Professor Tad Pfeffer, a study co-author. “But it’s like a little bucket with a huge hole in the bottom: it may not last for very long, just a century or two, but while there’s ice in those glaciers, it’s a major contributor to sea level rise,” said Pfeffer, a glaciologist at CU-Boulder’s Institute of Arctic and Alpine Research
ICESat, which ceased operations in 2009, measured glacier changes using laser altimetry, which bounces laser pulses off the ice surface to determine changes in the height of ice cover. The GRACE satellite system, still operational, detects variations in Earth’s gravity field resulting from changes in the planet’s mass distribution, including ice displacements.
GRACE does not have a fine enough resolution and ICESat does not have sufficient sampling density to study small glaciers, but mass change estimates by the two satellite systems for large glaciated regions agree well, the scientists concluded.
“Because the two satellite techniques, ICESat and GRACE, are subject to completely different types of errors, the fact that their results are in such good agreement gives us increased confidence in those results,” said CU-Boulder physics Professor John Wahr, a study co-author and fellow at the university’s Cooperative Institute for Research in Environmental Sciences.
Ground-based estimates of glacier mass changes include measurements along a line from a glacier’s summit to its edge, which are extrapolated over a glacier’s entire area. Such measurements, while fairly accurate for individual glaciers, tend to cause scientists to overestimate ice loss when extrapolated over larger regions, including individual mountain ranges, according to the team.
Current estimates predict if all the glaciers in the world were to melt, they would raise sea level by about two feet. In contrast, an entire Greenland ice sheet melt would raise sea levels by about 20 feet, while if Antarctica lost its ice cover, sea levels would rise nearly 200 feet.
The study involved 16 researchers from 10 countries. In addition to Clark University and CU-Boulder, major research contributions came from the University of Michigan, the Scripps Institution of Oceanography in San Diego, Trent University in Ontario, Canada, and the University of Alaska Fairbanks.
Built by Ball Aerospace & Technologies in Boulder, NASA’s ICESat satellite was successfully operated from the CU-Boulder campus by a team made up primarily of undergraduates from its launch in 2003 to its demise in 2009 when the science payload failed. The students participated in the unusual decommissioning of a functioning satellite in 2010, bringing the craft into Earth re-entry to burn up. ICESat’s successor, ICESat-2, is slated for launch in 2016 by NASA.

New dog regs in OSMP lands take effect April 15
Apr 13th
The first in a series of changes to dog management practices in the West Trail Study Area (West TSA) will take effect on Monday, April 15. The following areas will be posted with signage reflecting the following changes:
- Fern Canyon Trail (from where it leaves the Mesa Trail heading west to Bear Peak – Dogs on this trail will now be allowed to be off leash with the proper use of voice and sight control
- Lower McClintock Trail (from the wooden bridge just below the Chautauqua Auditorium along the short distance heading west until the Enchanted Mesa Trail) – Dogs will no longer be allowed on this portion of the trail
- Boy Scout Trail (located at the Flagstaff Summit) – Dogs will no longer be allowed in this area
These changes are the result of recommendations made and approved in 2011after a rigorous public process that brought constituencies together in the form of a Community Collaborative Group to develop a set of best visitor activity and environmental protection practices for the valuable ecosystem in the west TSA. Generally speaking, the West TSA covers from Eldorado Springs Drive (south) to Linden Avenue (north) and from Broadway (east) to the west side of the Flatirons.
The group made these recommendations related to dog management, as well as others that are likely to take effect around May 1. These will include the following changes:
- Towhee Trail – Dogs will no longer be allowed on this trail
- Old Mesa Trail (from Lower Shadow Canyon down to Eldorado Canyon) – Dogs must be leashed and on trail
- The Homestead Trail – Dogs will continue to be permitted off leash with the proper use of voice and sight control except for when crossing the riparian corridor, where dogs must be leashed
Be sure to check http://www.osmp.orgfor the exact dates when these future changes will go into effect and for general information about the provisions. If you have additional questions about these changes, please contact Dean Paschall at 720-564-2050.
