The JMT was built long before the PCT was completed; the PCT shares much of the JMT tread from Crabtree Meadows to Tuolumne Meadows, except the stretch between just N of Devils Postpile to Thousand Island Lake... The JMT designated southern terminus is the Mt. Whitney summit, the northern terminus is Happy Isles in Yosemite Valley...

With a little planning, plus knowing that hanging might dictate your daily trail miles - one can hammock every night... But some above treeline locations 'call out' to be able to see the sunset (or sunrise) - thus being able to also go to ground gives the best of both sleeping modes for traveling the 'High Sierra'...

Happy trails!!!
