That.is.brilliant. Thank you. I've been too lazy to go hunting around for topo maps outside of my own area. Its almost too easy now!

Now all I need is a nice printer...and some plastic ripstop paper to print all these on!..oh yeah, and people under the age of 100 to get out there with....small details...thanks a million!

I like having a real map in my hands and don't have access to a good printer.
What brand maps do people use in mountains?

I use SIMP 1:50,000
Not to sure if that's the brand name or not.
I like them as they show pretty much all the routes on them and where you can get water most of the time.
My one beef is that the elevations arn't marked very often on the contour lines though.
