Every stream, river, lake, and waterway within the drainage basin of the Mississippi-Missouri system, rendered in black and white. Data are from the USGS Hydrological Map layer. Available as a framed or unframed print or a super-cool metal print. Looks best large. The version shown here is highly compressed in order to not take all day loading on the page. The actual image is substantially sharper. The metal print option works especially well for this image.
