4-576: Schriebers Meadow Cone is a small parasitic cone on the southeastern flank of Mount Baker in the U.S. state of Washington . It was formed about 9,800 years ago by the only known Holocene flank eruption of Mount Baker. A basaltic lava flow traveled down the Sulphur Creek valley and across the Baker River valley; this is the most recent lava flow at Mount Baker. Future eruptions from Schriebers Meadow Cone are unlikely to occur as it
8-402: Is considered a short-lived feature. Schriebers Meadow Cone produced thick dark-reddish-brown to yellowish-red scoria that blankets the sides of the Sulphur Creek valley near and southeast of Schriebers Meadow. Near Schriebers Meadow the scoria deposit is thickest on the north valley wall and it decreases in grain size and thickness within short distances. Within 0.62 mi (1.00 km) of
12-420: Is the cone-shaped accumulation of volcanic material not part of the central vent of a volcano . It forms from eruptions from fractures on the flank of the volcano. These fractures occur because the flank of the volcano is unstable. Eventually, the fractures reach the magma chamber and generate eruptions called flank eruptions , which, in turn, produce a parasitic cone. A parasitic cone can also be formed from
16-498: The cone the scoria fragments are as much as 9.8 in (25 cm) in diameter and the deposit is 20 to 39 in (51 to 99 cm) thick; 3.7 mi (6.0 km) to the northeast the fragments are of sand size and the deposit is no more than 1.2 in (3.0 cm) thick.
