Lava Flow Hazards at Mount Baker

Mount Baker is largely constructed of lava flows, with the youngest summit lava flows (between 12,000 and 14,000 years ago) found in the Baker and Sulphur Creek drainages and perhaps in the Glacier Creek drainage. The most recent lava flow at Mount Baker is about 10,000 years old and is from the Schreibers Meadow cinder cone. It moved down Sulphur Creek valley and across the Baker River valley. Cinder cones, like the Schreibers Meadow cone, are short-lived features and it is doubtful that new lava flows will issue from this vent. If a lava flow emanates from a vent high on Mount Baker, generation of secondary lahar would be a concern, because snow and ice could flow down slope and remobilize loose material on the volcano's flanks.
