"Climbed east ridge of father dyer, and traversed to crystal and peak 10 and descended east ridge of peak 10 to wheeler trail and back to Spruce Creek trail. Some short fun scrambling sections on the father dyer east ridge!" - Peak 10, tylerburg, Aug 27, 2016
"I walked over to Bard Peak from Engelmann via Robeson. The wind was gusting strongly so I only stayed for a few minutes. As I was leaving the summit I saw a small snake moving across the gravel. I never knew that snakes existed at 13K in Colorado!" - Bard Peak, WaxDr, Jul 16, 2016
"I came to Argentine Peak from Square Top, passing under the high tension power lines that bisect the ridge. The summit has great views of Grays and Torreys. I considered going further to Edwards, but it looked really far so I settled for Wilcox." - Argentine Peak, WaxDr, Jul 9, 2016
"From Guanella Pass, I made Square Top's summit in two hours. I continued on to Argentine Peak and Wilcox before dropping down to Silver Dollar Lake and looping back around to Guanella's summit parking lots." - Square Top Mountain, WaxDr, Jul 9, 2016
"Great evening hike! Despite the holiday weekend, we enjoyed the summit all to ourselves around 5pm. Had some hail/snow near the summit on our way up and down. Slowly made our way down on lesser steep slope on the SE ridge and headed to square top lakes for sunset. Got back to the trailhead around 8:15pm and the milkyway was quite stunning. I'm going to have to come back to guanella to shoot the milkyway at some point. Pretty fun day and no crowds like on bierstadt!" - Square Top Mountain, tylerburg, Sep 6, 2015
