Thanks for sharing your experience, I hadn't considered the Echo Creek trail. I'd prefer to do a loop, but I can't figure out a way to get everything in with the time I have. I've posted a map showing the alt. route in red (I don't know if it will show up in the small size), I believe the trail you are talking about veers E and then SE from the JMT under two miles from Sunrise creek, is that correct? That pond sounds like a cool spot to stop at.
How is the sunrise creek area for campsites? I had chosen it as I am a bit concerned with the availability of water looking at the map, but if it is pretty busy as a stopping point for backpackers climbing Halfdome I might want to look into somewhere else.
