Data Story
About Soil in Custer County, South Dakota
The rugged soils of the Black Hills
Custer County's complex topography means soil data is limited and varies wildly by elevation. While a specific average pH is not available, the surrounding mountain soils often vary from acidic forest floors to alkaline valley floors.
Variable textures across the peaks
Specific percentages for sand, silt, and clay are not mapped in this dataset due to the rocky terrain. The soil texture here ranges from thin, rocky layers on ridges to deeper sediments in the mountain meadows.
Organic life in the forest
While available water capacity and organic matter averages are N/A, the region's forests suggest pockets of rich organic litter. Gardening here often requires raised beds to overcome the shallow, rocky soil typical of the area.
Fast runoff and mountain drainage
Hydrologic data is limited, but the steep slopes of Custer County generally lead to rapid water runoff. Proper site selection is key to finding areas where water and soil actually collect.
Gardening in zone 5a
Despite the rugged land, Custer sits in Zone 5a. You can grow beautiful mountain gardens featuring native wildflowers and cold-tolerant herbs, provided you have enough soil depth.
