The Prettiest Map of the Week

This Geologic Map of the Grand Canyon wins the prize for the most gorgeous map of the week. The map uses the Leaflet mapping platform with USGS data to create an interactive geologic map of the Grand Canyon.

If you mouse-over the map the make-up of the geologic strata at that location is automatically displayed on the map. If you click on the map the map scrolls off the page to present a more detailed breakdown of the geographic strata at the selected location.
