Localized flooding on Hidewood Creek near Estelline, SD, on June 23, 2013. Severe storms during June 21-22, 2013, in eastern South Dakota resulted in high flows in several streams across the area. The peak discharge on Hidewood Creek (streamgage 06479640) from this storm event was about 4,200 cubic feet per second.

This geologic map of Mauna Loa shows surface flows that have been mapped as of 2013. The flows are color-coded to reflect age. Warm colors indicate younger flows, with red indicating flows erupted since 1832. Cooler colors indicate older flows, such as at South Point, which is covered by flows ranging from 7,000 to more than 21,000 years old (blues and purple).
