author
A practical early guide to exploring Lassen Volcanic National Park, this author wrote with the eye of a naturalist and the clarity of someone who wanted visitors to notice more than just the scenery. His work remains a small but vivid window into mid-century park travel and outdoor education.

by Stephen Halsey Matteson
Very little biographical information about this author is easy to confirm today, but Stephen Halsey Matteson is known for Lassen Trails: A Brief Guide to the Trails of Lassen Volcanic National Park. The book was produced in 1963 by the Loomis Museum Association and was written as a compact field guide for people walking the park's trails.
The book's voice is practical, friendly, and observant. It gives readers trail details while also pointing them toward Lassen's geology, plants, wildlife, and changing seasonal conditions, suggesting that Matteson approached the park as both a guide and an interpreter of the landscape.
Because reliable personal records are scarce in the sources available here, it's best to remember him through the work itself: a concise nature guide meant to help ordinary visitors experience Lassen more closely and confidently.
