Survey Mark hunting on a Volcano 💥Obsidian Butte was a cool pile of rocks with a pre-historic history, + lots of marks found along the way!

A short hike on the PCT Grassy Hollow Trail to look for an Mt. Baden Powell Bench Mark gives me a little more than I bargained for.

Over the course of 3 outings, I was able to recover 7 of 9 Survey Marks for the Mount Woodson Station. Check this out to see what I found!
