Is there a preferred map package that people use for the JMT? I'll go doing it in July, from Cottonwood (S of Whitney) to Tuollumne Meadows.
On another issue, how do JMT hikers have a food drop taken in at Onion Valley? I think I remember a horse packing option.

I got the Tom Harrison map pack, but didn't carry it on my hike. I carried Trails Illustrated maps 206: Yosemite, 809: Mammoth Lakes - Mono Divide, and 206: Sequoia - Kings Canyon because I'm a map geek and wanted to have larger maps so I could see all the bail-out points/trailheads for future hikes. The popular Onion Valley resupply this year was from Mt. Williamson Motel - mtwilliamsonmotel.com/resupply/ Horse packing is also available but it's expensive and you don't get a night in a hotel.

For reference - I hiked from Whitney Portal to Happy Isles in 20 days. 1 resupply and lodging at Muir Trail Ranch. 1 unplanned but welcome zero in Mammoth Lakes, were I picked up a few supplies but didn't ship anything.

Toejam, thanks. How many miles per day did you hike, on average? I was thinking of getting a permit for 22 days.
HS Fan, that looks great. I'm not sure I want to trust battery life for navigation, but some kind of light weight map would be nice. Maybe a map on both sides of map paper.

My impression is on the JMT "navigation" isn't much of an issue beyond waypoints and key goals which may easily mean a very low frequency of referencing the map. Basically "follow the rut"....
Beyond that were I going that route I'd possibly look at a mapping GPS, have the 1:24k detail typos on it, standard AA batteries so power wouldn't be an issue backed by some overview sheets as a backup (the larger NG ones perhaps?). Perhaps if you're picking up supplies, with the sections for the next portion mailed in the supply package.
The one usage I find for the detail topo gps display is making off trail, WAY off trail (unless you like sleeping in piles of other through hikers....), campsite selection a bit easier.: I take my GPS, zoom in and "point" the thing so the display is showing what's over the promising ridgeline, meadow (so I change the setting from the top of the display being north to the top being where I'm pointing it), flat slabs etc. and get a selection out of the way without a lot futile climbing up and down. I'm familiar with how the Sierra terrain works so my guesses are usually pretty good anyway, but sometimes there's a better place off in a different direction I would have otherwise missed.

The Tom Harrison map set is probably the most popular. It's light but large enough for older eyes. Lots of people journal on the back sides. I wasn't trying to save weight and I look at maps for entertainment. There are a lot of options if you look around, especially electronic.
I averaged about 13 miles/day, but had a couple of long days. Take as many days as you possibly can and stop at all the popular spots. I feel like I was on my buddy's schedule and camped in a lot of crappy spots while running through places I wish I spent more time. It would be great if you gave yourself enough time to get off the trail for great camps as HSF suggests.

We used the Tom Harrison map pack. I folded my maps in 1/2 and carried them in a 6 x 9" manila envelope. To save weight, you could copy the maps, printing both sides, on standard 8 1/2" x 11" paper...

Putting your maps in a gallon ziplock allows you to see them while it is raining, and not get them wet.
