During the summer months, the Monument's Ranger Station features a bookstore, operated by our non-profit partner, the Eastern Sierra Interpretive Association (ESIA).
When the Ranger Station is open during the summer season, visitors can purchase maps, guides, books, and other materials related to the Postpile and Sierra Nevada. Cash, check, and most major credit cards are accepted for purchase. Proceeds from all sales go directly to support education and research in Devils Postpile National Monument.
If you would like to purchase items when the Ranger Station is closed, or during the off-season when heavy winter snows block access to the monument, you can purchase items at the Mammoth Lakes Welcome Center in the Town of Mammoth Lakes or online. For more information, please visit ESIA's website, or call them at (760) 872-1220, Monday through Friday, 8:00am to 4:30pm (Pacific Time).
