I had a BBQ to attend the previous day, which made my plans for a two-day trip to the Skamania CoHP and High Rock harder to accomplish... so I turned it into a long single-day excursion. Who needs sleep? Apparently, not me... zzzzzz... I immediately left the BBQ, drove down 5+ hours for the Skamania CoHP, and then a while later did that... it took 9-1/2 hours roundtrip using the Stagman Ridge approach. Then I immediately drove far north, and then east, to the High Rock trailhead and summited that mountain. I was glad to get the Skamania CoHP and the Lewis CoGPP out of the way in one trip. The southwest approach route for Skamania CoHP was VERY straightforward for me. Highly recommended!!!
