I co-led an adobe restoration project for Cornerstones Community Partnerships at Death Valley National Park. We restored a section of an adobe boundary wall which was built by the CCC in the 1930s. Americorps and various university programs supplied volunteers to help make blocks and build the wall. We employed a double-wythe (16 inch wide) adobe wall technique using natural adobe bricks and mortar. All of the adobe blocks used for this phase of the project (about 3,000) were made on site by hand. Special lime-stabilized adobe blocks were also made on site. The lime blocks were set at an angle to cap the wall with a weather-resistant "roof" to help shed rain and protect the adobe wall below.
