Keeping a nature journal is a good way to learn about your place and keep track of the many natural changes over the seasons. When did those white throated sparrows come through Unison last Fall? With your nature journal, you'll know when. The Murie Center published a book several years back called Field Guide to Journal Writing in Nature , by Matt Daly, that is a good primer.
It's also a good way to record those trips to places you're not used to. We recently had the chance to see the original journal the great field biologist George Schaller kept when he went in 1956 to what is now Arctic National Wildlife Refuge. It was fascinating stuff.
