Cuban treefrogs have leaped into Louisiana
Non-native Cuban treefrogs have established a breeding population in New Orleans, Louisiana, the first such population on the U.S. mainland outside Florida. The treefrogs were discovered at the Audubon Zoo shortly after a shipment of palm trees from Florida were planted in the zoo's elephant enclosure in 2016.

Biologist John Tertuliani making a high water measurement
Biologist, John T. makes a high water measurement at stream gage 03145484 Raccoon Creek near Granville, OH. High water measurements ensure accurate flood forecasting by NOAA for downstream citizens and property owners. These forecasts can help people prepare for the rising waters, help reduce property damages, and most importantly save lives.

USGS Station 011058798 Herring River at Chequessett Neck Rd gage house
This is a downstream view of the Herring River from the Chequessett Neck Road dike. The site was visited on November 6, 2017 to collect water-quality samples. An automated sampler inside the gage house was used to collect samples over an approximately 24-hour period and combine them into two bottles.

Previous Evidence of Water on Mars Now Identified as Grainflows
This HiRISE image cutout shows Recurring Slope Lineae in Tivat crater on Mars in enhanced color. The narrow, dark flows descend downhill (towards the upper left). Analysis shows that the flows all end at approximately the same slope, which is similar to the angle of repose for sand.
