Graphical abstract of the new research paper. The scientists collect samples from the rocks forming near hot springs and geysers. They dissolve small amounts of the rock in acid and organic carbon (created by living organisms) remains behind.

Flooded gaging station on the Souris River near Westhope, North Dakota, April 20, 2011.  See other pictures in this gallery with the tag 05124000 to see what the gage house normally looks like - it is on a raised platform on the bank of the river with an access road next to it.

Would you know there is a boat ramp here?  Launching a boat during high water on the muddy Missouri River requires intimate knowledge of boat ramps.  The Glasgow, MO, boat ramp (pictured) is underwater when the local gage is approximately 29 feet.
