Two things not mentioned:

Here's a link to some on-line maps:   Topo Maps of the MR and Main Trail


And you might like to just print one from your computer screen. Here's Mt. Whitney on www.postholer.com.

In both cases, a good color printer are especially good.

Two years ago, I created a set of maps for a PCT hike using Topo, then printed them on waterproof map paper. It's amazing stuff: looks and feels like paper, but try to tear it and it is pvc plastic! And whatever you print on it will not wash off. Of course, the stuff costs about a dollar a sheet.
