Natural Shifts in the North Cascades
The sheer power of water was apparent in the North Cascades this last weekend after a recent Pineapple Express hit the Northwest. Warming temperatures combined with a significant amount of rainfall fell onto several weeks worth of snow in the Cascades. Consequently, mountain creeks filled to the brim and several landslides covered Highway 20, closing a stretch of this road between the towns of Diablo and Newhalem. Several M.Ed. graduate students and our graduate coordinator were staying at the North Cascades Environmental Learning Center and in the town of Diablo, and got to see this dynamic shift in nature first-hand.
At the Learning Center, the recent weather demonstrated how quickly land is shaped by water as we watched Sourdough Creek quadruple in size Sunday afternoon. This was an amazing shift to see as Sourdough typically runs as a trickle in late summer to a swiftly-flowing mountain creek in late spring. Sourdough Creek runs next to the Learning Center’s parking lot under a “Texas dip,” a removable piece of roadway designed to prevent washout. But this road feature was barely recognizable as the creek filled with brown, fast-running water that undercut the bank, causing large chunks of earth to collapse and wash away into Diablo Lake.
