National Park Field Guide

The National Park Field Guide from the National Parks Conservation Association offers comprehensiv information about 50 national parks.

The interface is easy — you simply scan a map, find your park and click through to information about the wildlife found there, general information about the history of the park, and contact and mapping information. It's been installed on my iPod since it came out and was handy earlier this year on a trip I took to a park in nearby New Hampshire.
