Map of saturated hydraulic conductivity at a 5-cm depth for the contiguous United States. This map shows large-scale variation with high conductivities on coarse materials (orange-red, such as Florida, mountains, glacial sediments) and low conductivities on the fine sediments in the U.S. interior (blue). Actual map holds 49,810 × 31,390 pixels (West–East × North–South) at 100-m resolution. Image by Marcel G. Schapp, Yonggen Zhang, and Craig Rasmussen.
