From across the water, the western shore stands out in sharp relief. Bright white bluffs gleam in the summer sun like the White Cliffs of Dover. But when you approach by water, you’ll see that the cliffs are not rock at all, but sheer walls of Solvay waste. While your boat bobs on the waves, you can see erosion gullies in the wall, the weather conspiring to mix the waste into the lake: summer sun dries out the pasty surface until it blows, and subzero winter temperatures fracture it off in plates that fall to the water. A beach beckons around the point but there are no swimmers, no docks. This bright white expanse is a flat plain of waste that slumped into the water when a retaining wall collapsed many years ago. A white pavement of settled waste extends far out from shore, barely under water. The smooth shelf is punctuated by cobble-sized rocks, ghostly beneath the water, unlike any rock you know. These are s, accretions of , that pepper the lake bottom. Oncolites—tumorous rocks.
