If you click and zoom in to the area you want to research, then click the AOI button and drag a square/rectangle on the map creating your area of interest, you can then click the tabs such as soil data. I love this website, it contains tons of information such as the soil horizon (layers) types and depth, depths to obstructions like bedrock, water infiltration rates, and more. Hope this helps you out!
