Here was Tuolumne Meadows near sunset on Tuesday 6/5. Temperature was near freezing.
On Wednesday 6/6 I headed east from Tioga Road towards Medicott Dome. I headed south below the cliffs around 8800 feet. I came out alongside the outlet of Lower Cathedral Lake. Headed up to the base of the falls and crossed the stream(may be difficult if the stream was bigger). Headed south and up a dirt slope to more cascades above. Made it to the base of the upper falls without too much trouble. The last 100 feet up to Lower Cathedral Lake was a bit tricky going up a steep cliff. With careful route finding I was able to follow cracks and use a trekking pole to make it up the steep cliff(I probably wouldn't want to come back down this way).
