![]() ![]() The library worked with regional historian George Cearley to identify important features in the photographs such as major roads, railways, and landmarks. These photographs are part of the Foscue Map Collection. Most of the photographs are taken at an oblique angle and at a closer range than the aerial photographs in the Dallas Historic Aerial Photographs and the Dallas Aerial Photographs, 1945 USDA Survey collections. In fact, some of Long's photographs were used in documenting the new levees' effectiveness in an article published by the Dallas Morning News in May 1935. Of note are the images of the flooding of the Trinity River in 1935 and in 1941. The collection demonstrates Long's interest in civil engineering and industrial subject matter, exemplified in the images of the Trinity River levee system, the KRLD and WBAP radio transmitters, the Carrollton Dam, and the Mountain Creek General Station. The photographs include various images of Dallas, Mountain Creek Lake, White Rock Lake, and the Trinity River, including two aerial surveys (multiple photographs that fit together to make one overall image) of White Rock Lake and the White Rock Creek area. There are 41 aerial views in this collection, representing photographs taken by Lloyd Long in the 1930s and 1940s.
