The East Buttes are made up of several extinct volcanoes in and around Gresham, Oregon, United States, which are part of the Boring Lava Field. The Boring Lava Field became active at least 2.7 million years ago, and has been extinct for about 300,000 years. The buttes stretch from southeast Portland into Damascus. Included are Gresham Butte (also known as Walter's Hill), Gabbert Hill, and Towle Butte. Much of the land on Gabbert Hill was previously designated for a subdivision called Darby Ridge, but was acquired by Metro and the City of Gresham in 2007.
