Lake Erie Islands
The Lake Erie Islands are a chain of archipelagic islands in Lake Erie. They include Kelleys Island, Pelee Island, the Bass Islands, and several others. The majority of these islands are under the sovereignty of Ohio in the United States. Pelee Island is the only major island administered by Ontario, while the smaller Middle Island is the southernmost point in Canada. Most islands that are large enough are popular tourist attractions with car ferries running from the mainland and between some islands and some small airports and numerous private marinas offering other ways to reach the islands. Combined with nearby Sandusky and Port Clinton, Ohio, the islands are part of the collective area known regionally as "Vacationland".
The Lake Erie Islands are geologically part of the Silurian Columbus Limestone. When the Pleistocene ice sheets carved out the basin of modern-day Lake Erie, these hard rocks proved more resistant to erosion than the shales in the east, and as a result, Lake Erie's western end is much shallower than the basins in the east, so that the islands remain above water. Quarrying operations on Kelleys Island revealed glacial grooves in the bedrock, which would in time be regarded as some of the best direct evidence of the Pleistocene ice sheets available anywhere. The glacial grooves are now protected as part of Kelleys Island State Park.
