At the tip of the Point, the 1960s-era repair was essentially a giant concrete block formed on top of crushed limestone. The concrete has held up for forty-four years, but the wave action under the concrete has eroded away the sand under and behind the steps of the revetment, causing the limestone blocks to sink "back first" into the lake...
The bottom has fallen out in this spot:
Swimming access at the Point was not part of the original Burnham plan. Erosion and shifting limestone blocks have created "step stones" that we clamber over to get into the lake. We love swimming there, but it's a flawed system, at best:
But I digress.
Here you can see the skeleton of the steel girders and wood pilings that used to hold the limestone blocks in place:
The wood pilings were large logs when they were installed, and are mere snaggle-toothed remains now. You can see these rotted pilings in every section of revetment, even in places where limestone blocks seem to buffer the wave action:
Lake levels are at a historic low, but if you visit the spot below and walk on the dry rubble along the water's edge you'll see that even on this southern, "protected" side, the girders and pilings are gone, and there's a gap forming under the limestone promenade:
