I think she cleared Muir Pass today. Last post was at 1 pm, just a mile from the summit.
To use that
SPOT map:First, click on the top (last) orange dot on the list of "messages" in the left column. That causes the map to "center" on her last location.
Then, click on "Terrain" (upper right corner). That switches to a topographic map.
Last, zoom all the way in. The last two zoom levels show the JMT on the map.
