Rocky Mountain Tree Finder: A Pocket Manual for Identifying Rocky Mountain Trees: Finder

Learn to identify native trees by their leaves and needles in the Rocky Mountain region. Like other pocket guides from Nature Study Guild Publishers' Finder series, this book is organized as a dichotomous key. The key leads you step-by-step through a series of simple questions to arrive at the name of the tree.
Area covered extends across the mountain West, from the Canadian Rockies on the north to the mountains of New Mexico and Arizona on the south, and across the Rockies and Great Basin, from the Black Hills on the east, to the eastern slopes of the Cascades on the west.
New in the 2008 second edition: Scientific names updated. Range maps extended to include the Canadian Rockies. Metric measurements added.
