Nice pictures. Thanks!!
I was hiking early last week on a loop from Garnet Lake, east over a pass down toward Nydiver Lakes, and down the drainage to Ediza. Then around to Garnet via the JMT. Long 9-hour day. As we were hiking down the creek from Ritter & Banner, a hiker descended and passed us.
He had left Agnew Meadows at 2 AM, climbed Mt Ritter, and was headed back to Agnew Meadows -- all as a day hike. I am sure he made it seeing the speed he was hiking. He was a radiologist dude from Fresno & Oakhurst.
Here he is, in the background, and the two I was hiking with.
