KLICKITAT COUNTY AREA is in the south-central part of Washington. The Columbia River lies along the southern margin of the area. The northern boundary begins on the southeastern flanks of Mount Adams, extends over the Simcoe Mountains, and follows the crest of Horse Heaven Hills. Elevation ranges from about 70 feet along the Columbia River to about 5,900 feet at the top of the Simcoe Mountains.

 

The area is 84 miles long and 13 to 29 miles wide. It has a total area of 1,013,863 acres, or 1,583 square miles. About 24 percent of the area is cultivated, 42 percent is rangeland, and 34 percent is forestland. The major crops include small grain, grass and legumes grown for hay and pasture, and orchard crops. About 32,333 acres are irrigated. About 137 different kinds of soils are in the survey area.

 

A majority of the soils formed in loess and colluvium and residuum derived from basalt. Some soils formed in alluvium, eolian sand, and lake sediment. Most of the soils are very deep and well drained; however, many soils in the eastern part of the survey area are moderately deep or shallow over basalt. Some soils in low-lying areas have restricted drainage and are affected by wetness or excessive salts.

 

An old unpublished soil survey covers most of the survey area. This present survey updates the earlier survey. It gives additional information and provides maps that show the soils in greater detail.

 

Today, soil surveys are no longer published in book form; they are published to the web and accessed on NRCS Web Soil Survey where a person can create a custom soil survey. This allows for rapid flow of the latest soil information to the user. In the past it could take years to publish a paper soil survey. The information in a soil survey can be used by farmers and ranchers to help determine whether a particular soil type is suited for crops or livestock and what type of soil management might be required.
