- Dishman Hills Natural Resources Conservation Area (dnr.wa.gov)
Impacted by flooding from Glacial Lake Missoula in Montana, the resulting landscape of scoured out potholes, ponds, ridges, and gullies support grassland ledges speckled with ponderosa pine and habitat for one of the last remaining populations of water howellia, a threatened plant in Washington State.
- Glacial erratic boulders of Island County, Washington (Wikipedia)
Glacial erratic boulders in Island County are a remnant of the Pleistocene glaciation that created Puget Sound and transformed the surfaces of what are now Island County’s main landmasses: Whidbey Island and Camano Island. South of Deception Pass, the two islands’ surfaces and beaches are completely composed of glacial till. Abundant glacial erratic boulders lie on the islands, their beaches, and under the near-shore waters.
