The MacDonald Properties (1972-1996) series consists of materials that document the planning and development of MacDonald Ranch, but are not specifically related to the communities of Sunridge or the Foothills. These materials include architectural drawings, master plans, land use studies, water supply plans, topographic maps, tentative maps, and preliminary reports.

The Tapping the Colorado project series (2021-2024) is comprised of 268 color images representing a range of aerial photography documenting the historic critical water levels in Lake Mead and Lake Powell in 2021 and 2022. Stillings' artist statement and curriculum vitae are also included in this series.

This collection of aerial photographs focus on the Colorado River, Lake Mead, and Lake Powell. They were created in 2021 and 2022 as part of Jamey Stillings' series titled Tapping the Colorado. This selection of images is described by the photographer as "Prime Images for Exhibition and Publication," and he notes "The artist intends to exhibit and publish these images." This portion of the "Prime Images" focuses on Lake Mead, Hoover Dam, and the Colorado River.
