The image below is generated by overlaying the JMT on a base map. It is currently focused on Horseshoe Meadows. This is at about 10’000 feet and provides a good view of the snow conditions at the start of the JMT going northbound. Currently, this image is getting regenerated about once a month. Although this is fun to look at in the early season, conditions can change so rapidly that it’s not a good indicator of snow conditions for the trail until late spring.
May 2022 – Full JMT
By May – Horseshoe Meadows is completely clear. Indeed early PCT hikers have already crossed the Sierra and reported that in the southern Sierra – especially south of Forester Pass – the trail is very much clear. North of Forester Pass there is still a considerable amount of snow on the trail.
