The normal USGS topo map for the area is fine. I"m taking this off of memory but I think the 7.5 minute version is called North Palisade Peak (NOT Brower Palisade... sorry I had to throw that in for anyone who is familiar with the proposed renaming).
I think the hike is about 8 miles to the glacier one way so you're probably looking at a hike over your 12 mile limit. You can shave some of this distance off by parking in the day use area if you're doing a day hike. I'm guessing that would cut about a 1/2 mile each way off the hike.
It's a beautiful area. Have fun on a great hike!
