KTH is on Wickersham Dome, near the end of the Park Road in Denali National Park. This site is generously hosted by our partners at the National Park Service. KTH was installed in 1988 and upgraded to digital broadband site in 2003 as part of our network improvements in response to the 2002 M7.9 Denali Fault Earthquake. KTH is one of four seismic stations inside Denali National Park.
