Near Pomeroy in Garfield County, Washington — The American West (Northwest)
"the Soil is extreamly fertile"
After breaking camp on May 4, 1806, a cold and disagreeable morning, the Lewis and Clark Expedition crossed 'Alpáha (Alpowa) Summit, just north of here. The explorers noticed the rich soil of this country. Lewis wrote, "the lands through which we passed today are fertile consisting of a dark rich loam."
American Indians harvested a variety of plant growing in the rich soil, One of the most important was blue-flowered qém'es (camas). The Expedition "observed considerable quantities of the qua-mash in the bottom through which we passed...now in blume."
Today, this area is one of the world's most productive agricultural regions. Farmers grow wheat, dry peas and lentils, barley, and numerous other crops. American Indians continue to harvest qém'es in wet meadows of this area.
Flower Power
Qém'es (Camas) has always been an important plant to native peoples. The plant's bulbs are nutritious, making them an important food source and trade good throughout the West. On numerous occasions, members of the Expedition obtained qém'es in various forms (dried, powdered, boiled, etc.). Qém'es flowers can be seen throughout this region in late spring. Vast "seas" of vibrant blue color are a treat to eyes accustomed to endless hills of green and brown.

Soils are made up of sand, clay, and silt. You can tell what is in the soil by its texture. Soils with a lot of clay feel sticky and stay together when packed. Soils with a lot of sand feel loose and gritty. Loam soils are a mix of clay, silt and organic matter. Can you tell what is in the soil here.

1. Camas (plant) - Discovering Lewis & Clark. At Weippe Prairie on June 11, 1806, while waiting for the snow to melt on the high ridges of the Bitterroot Range, Lewis found time to write one of the longest, most detailed descriptions of any of the plant specimens he collected.

2. The ethnobotany of Camas Lily -- Beautiful Oregon Photography. While the earliest evidence of human occupation of the Willamette Valley dates back to between 11,500 and 10,000 years before present (B.P.); the first known instance of bulk-processed camas lily occurs around 7750 to 6830 B.P. at the Hannavan Creek site near present day Fern Ridge Reservoir. Here near the Long Tom river, hundreds of intact, charcoalized camas bulbs were retrieved from the first known example of a stone hearth used to cook the bulbs.
