The Maritime-Influenced Zone is that part of the Blue Mountains (11) that directly intercepts marine weather systems moving east through the break in the Cascades (4) at the Columbia River Gorge. Rain or snow events occur except in the summer. Loess soils are found at lower elevations near the Columbia Plateau (10) and have a moderately high water holding capacity. Moisture availability is sufficient to support forests at lower elevations than elsewhere in the Blue Mountains (11). A xeric forest of ponderosa pine and Douglas-fir occurs and has a dense and diverse shrub layer beneath it.
