PHYSICAL: The reserve is on the floodplain of the Skagit River , a relatively small, fast-flowing river with a gradient of about six m/km. The northeast-southwest trending valley, located in the Hozameen Ranges of the Cascade Mountains, is bounded by slopes of about 30o which rise to peaks of 2100-2500 m. The valley is relatively

ORIGINAL PURPOSE To set aside unlogged floodplain islands for research on succession in black cottonwood communities. Physical: The reserve comprises three large and four small islands in a low-gradient reach of the Skeena River where reduced river velocities allow sediments from upstream to settle out, forming many bars and islands. The river is slightly sinuous
