Inscription. The furnaces of the earth brought spectacular change to this land 1300 years ago. A new, rough, glassy environment offered a harsh home for the heartiest plants and animals. Past cultures prized the shiny black rock for their survival. Today, the Big Obsidian Flow is marvelled at for its beauty and mystery.

Walk a few minutes on a paved trail for a “sparkling” panorama of the Big Obsidian Flow. Then, if you like, climb the stairs for a walk along the half-mile trail (0.8 km) on top of the flow through a rugged landscape of natural glass. It is not recommended that you wear sandals or take dogs on the trail because it is made of crushed natural glass.

Learn interesting facts about the Big Obsidian Flow of Newberry Crater from the interpretive signs along the trail:

• A Glass Menagerie
• The Eruption
• Tools for Survival
• People & Obsidian
• Life on the Flow
• Global Perspective
