The major distinguishing feature of the Wahluke Slope is its uniformity in aspect, soil type, and climate. The entire appellation lies on a broad, south-facing slope with a constant, gentle grade of less than 8%. This, along with the proximity to the Columbia River, helps minimize the risk of frost, which can affect other areas of the state.
