"I approached from Boreas Pass and walked up the south ridge from Black Powder Pass. On my way up I was startled by a mountain goat as I topped out on a false summit. I backed down the ridge and let the goat pass without incident. I continued on to Boreas Mountain before heading back to the pass." - Bald Mountain, WaxDr, Jun 30, 2018
"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
