The trail to Upper Yosemite Falls is steep and much of it is over easily eroded decomposed granite. On our recent visit there was a crew working to improve the trail.
It's not an easy job. First the granite must be cut from large boulders off the trail.
Then hauled by people power to where it is needed. This is wilderness so no motor driven equipment is used.
They set the blocks in place.
They build a wall, the old fashioned way.
It's hard work but oh! What a view!
We do appreciate their hard work, making the trail safer for everyone.
