Meanwhile, MRHS is collecting Coastal Station History
“But what did these stations actually look like? We here at the MRHS have collected as many photos of these historic stations as we could find and posted them here for your enjoyment. They range from many photos showing the big, well documented to a single photo for a small station that was in operation for only a few years.
Do you have photos like these you’d like to share? Please let us know. We’d be honored to post them.”
