Sample of juvenile block from block-and-as flows deposited on the debris avalanche formed during flank collapse of ancestral Mt. Spurr (“pyroclastic fan”; sample PF-45 of Nye and Turner (1990)). Sparsely phyric lava from large lava lens in yellow-orange debris flow/lahar in Canyon bottom. Lava unit is jointed and fractured on 5-30 cm scale. Lava lenses 10s or m long scattered throughout unit. Not the same unit as block-and-ashflow flow 2 canyons to west or S01.
