This was the original temporary GPS antenna mast (EDC1) at the first seismic station AVO installed on Crater Ridge in May of 2022. This mast slipped off its rebar marker in winter 23-24, and leaned heavily to the NE. We set it up again in August 2023 for 3 days to "tie" the old and new GPS time-series together. It was then removed.
