In the same way that the other mountains of the Cascade Range were formed. The Juan de Fuca Plate subducted under the North American Plate. The water that subducted with the Juan de Fuca Plate lowered the melting temperature of the rock above it, causing magma to form. The magma built up and rose, causing the formation of all the mountains in the Cascade Range.
