We only made it to Tortilla Pass (junction of JF Trail 106 and Roger's Canyon Trail 110). Members of our group weren't prepared for the steep ascent.
We hadn't seen any good water sources, so a group of us were planning to head down into Angel Basin at Roger's Canyon to get some water. Thankfully, some other hikers there told us there might be a spring just a little further northwest on the JF Trail. There was indeed enough water in Tortilla Creek to treat! Our trip was saved.
