K13K was installed in 2017 as part of the temporary USArray project and integrated in 2020 into the permanent Alaska network as part of the National Science Foundation-sponsored Alaska Geophysics Arctic Observing Network project. Located on top of a rise in the foothills of the Kusilvak Mountains, K13K overlooks the Black River. This small, isolated mountain range is surrounded by pond-riddled tundra. At one site visit the field team noted, "Corrosion was noteworthy on external metal components and cables. Courtesy of Bering Sea influence." Wildlife can be a challenge: previously at this site some wires were severed, possibly by a fox, and a bird had removed one of the weather sensors. Ice on the equipment can add an extra challenge in early spring. Photo courtesy of Array Network Facility.
