Chehalem Mountains

The Chehalem Mountains is a northwest-southeast span of several distinct mountains, ridges and peaks in the northern part of the Willamette Valley. Of all of Willamette Valley's smaller AVAs, it is closest to the city of Portland. Its highest summit, Bald Peak at an elevation of 1,633 feet, serves to generate cooler air for the rest of the AVA and its hillside vineyards. The region covers 70,000 acres but only 1,600 acres are planted to vines; soils of the Chehalem Mountains are a mix of basalt, ocean sediment and loess.
