A split-panel map of Salt Lake City, Utah, highlighting the Great Salt Lake, shows 2006 Landsat imagery on the left side panel and 2006 NLCD, with colorized legend of land use classes, on the right. The animation displays a slider being used to switch between the two different datasets, revealing the land cover classes shown in Landsat imagery.

A tile map of the U.S. with lollipop charts for each state that show differences in forest area magnitude, in squared kilometers, from the 35-year mean (1985-2020) across the contiguous United States (CONUS). Positive differences are shown in forest green lollipops and negative differences are shown in burnt orange lollipops.

Mean daily streamflow (cfs) of the Rio Grande at Embudo, New Mexico from 1991 to 2022. The chart has a black background and the 30 years of mean daily streamflow data are plotted as stacked white ridge lines that emulate the aesthetics of a classic rock album.

A tile map of the US showing streamgages by flow levels through the month of March 2023. For each state, an area chart shows the proportion of streamgages in wet, normal, or dry conditions. Streamflow conditions are quantified using percentiles comparing the past month’s flow levels to the historic record for each streamgage.

Waffle charts are colorized and faceted by contaminant (Pb, Fe, NO3-, and Sr) and region (West, Central, Midwest, East). Each 10 x 10 waffle charts shows the proportion of study area that contains high, moderate, and low concentrations where 1 square = 1 % of region. Figure contains callouts where, for example, NO3- in the Central U.S.
