Where is Snowflake Obsidian found?

Snowflake Obsidian occurs in specific geological environments. Knowing where to look, and in what kind of rock, is the difference between going home empty-handed and finding a great specimen.

Where to find Snowflake Obsidian

Collecting tips

1. Geological Context. Look for Snowflake Obsidian in areas with recent (Cenozoic) felsic volcanic activity, particularly near rhyolitic lava flows, domes, or volcanic necks. It often occurs in the outer margins of these flows where cooling was rapid.
2. Associated Minerals. It may be found alongside other forms of obsidian, pumice, and sometimes perlite. The surrounding rock will typically be volcanic in origin.
3. Surface Identification. The distinctive white 'snowflakes' against the dark glassy background are usually visible on weathered or broken surfaces. Look for shiny, dark fragments with these characteristic patterns.
4. Safety Precautions. Obsidian, including Snowflake Obsidian, breaks with extremely sharp edges. Always wear appropriate gloves and eye protection when handling raw specimens or breaking them. The dust generated from cutting or grinding obsidian (which is primarily silica) can be a respiratory hazard; use proper ventilation and dust masks (e.g., N95 or P100 respirators) to prevent silicosis. While the cristobalite is embedded, prolonged exposure to airborne cristobalite dust is a known carcinogen.
