In 2006, the Grand River in northeast Ohio experienced a flood so large that it is expected to only happen once in 500 years. This area was under several feet of flowing water that night, and you can still see some of the debris stacked here. However, there was a remarkably low loss of life, due in part to the fact that so few people live in the valley itself. The Outdoor Family Center, part of the Lake County Y system, has taken steps to make sure that this particular bit of floodplain will never be developed. If you do this cache series, you will see several landform features that are unique to floodplains like this, including terraces, oxbows, benches, wetlands, and even a bit of a yazoo tributary developing. There's also a bounty of interesting floodplain trees and native wildflowers in season. Odds are good you'll also encounter slick mud down on the bottomlands, but the hilly parts of the trails are well-gravelled.
The set can be done in numerical or reverse-numerical order. Or any other order, I suppose, if you want to retrace your steps. Terrain is rated from the parking lot, but once you're down the hill, it becomes more of a 2-2.5 star terrain. Caches placed with permission of the branch manager.
