Route & General Observations

I experienced a lot of small cracking underfoot on my uptrack. Did a few hand shears all with easy-moderate planner results around 10cm down. On a switchback I stomped and released a 7′ wide area. Once I reached 2040′ I was moving into Avi Terrain so I stopped and dug a pit.
