Ashland Breakwater Light

USGS Wisconsin Water Science Center

There it sits at the end of the breakwater in Chequamegon Bay, much as it has since 1915: the Ashland Breakwater Lighthouse.

But it's more than a tidbit of history or a photo op these days; it's part of the Apostle Islands National Lakeshore, a USGS weather station and home to monitoring equipment for everything from currents to water quality to time-lapse photography.
