Science Moab talks with researcher Phoebe Brown, studying growth rates of the humpback chub
Phoebe works to investigate how the endangered fish can thrive. The Little Colorado River has a brilliant turquoise-blue color due to the calcium carbonate minerals suspended in the water. Travertine, a chalky limestone that settles out of the water and coats the riverbed with a white hue, adds to the river’s amazing color. The Little Colorado River can be divided into the upper and lower reaches, with the boundary between the two marked by a series of travertine waterfalls. The river is one of the last remaining places where you can find the endangered humpback chub. Science Moab talked with Phoebe Brown, a river guide and researcher who as an undergraduate was part of a larger study looking at the growth rates of the humpback chub.
