How much has the JMT changed in the last 14 years?


 

I have the 2009 Harrisons map set which I bought for my 2010 JMT hike.? I see he no longer prints maps but you can buy them in electronic form, which I'm less wild about.? Has much changed on the actual route of the JMT in the last 15 years?? I know the regs and permits have changed a lot.? I presume these maps are perfectly fine but willing to be convinced otherwise.

Maps are maps since terrain does not change much over the years; exception is large slides. In terms of routes, sure there could be some shifts, but one should not rely on the map just for the route. I use old maps all the time. I do discover that trails become over grown and less used. I find these to be quite fun.

Map and compass are used to know where you are on the map. If the trail has shifted, so what you show to be off by a 100 yards or so. You know generally where you are and how to get out quickly in case of an emergency.

(I come from a search and rescue perspective working with search dogs.)

2009 should be fine. There might be some minor shifts, but I doubt you'll notice them and the overall trail is quite well marked.

Now if you had maps from the 1930's or so there would be some major route changes...? =)

Cheers!

Good for you using map and compass. Essential skills that get ignored by some. ? The JMT is very straightforward and easy to follow. ? I love when I fold one up and open up the next. ?Those maps are great and should be very acurate for 2024. ?I just got far out for the pct. No excitement in electronic map software?

I still use my Harrison Map Set from 2004. I add maps I print for alternate routes that aren't on the map set, like last years Piute-Bishop Pass alternate. Instead of getting a new map set I opted to get the FarOut guide for my phone.

As stated the Harris Maps are out of print but available for about $20 the set on Amazon.

You should be good with the TH maps (I was in 2017).?

I am also a compulsive user of CalTopo for route planning, which I used to plot side trips from the JMT, high water bypasses, etc. Depends how comfortable you are using apps for navigation (I appreciate some people would rather not), but CalTopo, Gaia, FarOut and others make JMT nav really easy. You can use the free desktop version of CalTopo to plot bypasses (for example, dead bridges), and print them to bring in hard copy (very nice route plotting and choice of base maps).

Have fun!

Sorry, I may have missed this, but what has changed about TH maps? I was alarmed to read that they were out of print, I use them by preference all?the time,

But looking at their website I don't see any indication of this and the copyright date at least has been updated to 2024 for the webpages:

I bought a set of Harrison maps in '96--they are still fine-simple and fine . . . The trail, the dusty part below your tread hasn't changed, other than the downed bridge diversion you must now do unless you are adventurous, but I see that as a great excuse for a night in Bishop, maybe a little hassle doing the ride thing, and a huff'n puff of a re-entry, but otherwise the trail ain't changed.?

Seems the maps have changed--the Harrison's always maintained simplicity, kind of get the job done, sort out the rest as needed, but it seems that of the other maps I have seen, if you need to know how many feet to the nearest pit-toilet, once you step off the trail, pit toilet in plain sight, there ya go. It could be argued, but there are lots of details in the new maps--if that's your thing, then . . .?

Aaron, they don't sell the TG paper maps for the JMT map set any more. You can still get the digital version and copy centers can probably print on tearproof tyvek paper.?

Inga


 

When printing, think about using a laser printer instead of inkjet. This way things do not bleed when wet.


 

When I go out hiking, I will load up a small set of CalTopo on my phone, but only as back up. Otherwise, I make sure my Garmin 64st is with me; batteries last longer than a cell phone in airplane mode. Then there is the paper maps that do not get terrain changes; path changes occur with I get there. Then practice mapping the change on your own map.


 

Thanks, yeah, I traded messages with Tom! A bit dismayed.

I love those maps... :.O

You can get what is claimed to be new sets on Amazon today. ?Mine supposedly will arrive mid Feb with a complete return guarantee.
?They don’t print them but have stock. ?We shall see ,

If the maps are so "up to date", will it include the bridge outage re-route?

They’re not “2023” up to date, can’t imagine any maps/apps include the dead bridge alternates as a standard re-route.

Inga and Derek-

It sounds like you two have experience printing your own waterproof maps? What's the process? Is it as simple as "laser print on tyvek (or equivalent) paper", or is there more to it? Any other tips? Thanks in advance!

-Ryan


 

Ryan - If out for a few days, I would print using a laserjet. Laserjet printers use plastic (hence the heating process to fuse the plastic onto the paper media) and will not bleed when wet. Inkjet printers are water-based and will bleed if wet.

Use of tyvek paper is nice for longer trips as the paper media withstands much folding and abuse. However, it is more expensive. Use tyvek if you are going to re-use your maps multiple time.

When I do a distance hike, I would use regular paper from the laserjet. The map only needs to last a few days before I move on to the next page. Then you can burn it to help start the camp fire.
