This is a trail we always end up at for snowshoeing! It has a lot of snowpack and is dog friendly, an essential for a good trail. Not too many people this day, it was snowing a bit but the conditions were great otherwise. More of a trail, not too much to see through the trees and the trail is a bit hard to navigate the dog friendly parts, but good overall!

I hiked a bit on the segment by Beaver Reservoir this month. There's an extended foot bridge over Beaver creek which is marked "Closed". This seems to be due to some missing/rotted boards and missing hand rail over the deepest part of the creek. It is safer than trying to ford the creek but it's definitely "use at your own risk".

As the description states, mainly used for trail running and mountain biking. This is a very strenuous trail that is not recommended for sight seeing or a nice leisurely family hike. This is a very difficult and extremely rocky trail.

Uphill trail that is fairly easy hike. About 15 minutes up you are allowed to camp and are currently allowed to have a fire. A buddy and I hiked in about 4 miles and camped over night was a good time and would do it again downhill was super easy!

Exit at University of Colorado Mountain research station, trail up ahead on right. This trail is very strenuous and 90% up hill, when heading north on trail. They call it north sourdough. Their are jagged rocks that cover whole trail all 6 miles up. It is fast down but beware, I am an advanced rider and my wrists killed me at the bottom and I'm on an all mountain bike. Little traffic also. Over all great ride, nice to get out city and hot temps and HIGH in the mountains :) 6/20/2012
