Long-time member here, SaltyDog, is on a great summer adventure. As I write this, he's closing in on the JMT on the Bear Creek trail, just south of Edison Lake.
On his "John Muir Route", his goal is to hike the Sierra in an alternate route to the JMT, to demonstrate to people that the JMT is not the only way to experience a journey through the Sierra Nevada range. People could follow his route, which would help alleviate the population pressure on the JMT.
He's carrying an InReach SE satellite unit that posts his location on his
garmin shared page. His trip started July 21, so you can set a filter to see only that trip on the web page (set filter date range: upper left, just below the "GARMIN").
Here's a map of his track between July 21 and today.
So far, he's not set foot on the JMT, except for two crossings in the Devils Postpile area. He'll need to use a part of the JMT to get to the trail toward Lake Italy today or tomorrow.
