The Old Bathhouse at Backbone
This old stone building at the Backbone beach was once the bathhouse, and I remember how it worked. I even had the privilege of filling in there for a few days, back when I was in high school.
You checked in and were given a basket with a numbered pin that fastened to your swimsuit. Then you entered either the men’s or women’s changing area, both open to the Iowa sky, and placed your clothes in the basket.
On the way out was another opening with a counter. You set your basket there with your clothes still inside, and it was placed on the shelves for safekeeping. You kept the numbered pin and ran down to the beach. There was little reason to walk when Backbone Lake was waiting.
When you finished swimming, you returned to the counter and handed over your numbered pin. They found the matching basket and passed your clothes back through the opening. You carried the basket into the changing area, got dressed and returned it on your way out.
It was a simple system, and it worked. So long as you kept hold of that little pin, you stood a fair chance of getting your clothes back.
The bathhouse was built by Civilian Conservation Corps workers in 1934 and 1935. The baskets, numbered pins and open-air changing areas are gone now, but the old stone building remains beside the beach, holding the memories of generations who once ran from there down to the lake.
I was fortunate enough to spend a few days working inside those walls when I was young. At the time, it was just a summer job. All these years later, I realize I had been handed a small place in the history of Backbone.
