Long lingering in the background, dwarfed by the posh amenities of state parks, the state's natural areas and preserves have become a focus of the Ohio Department of Natural Resources, which is hosting a series of events at them this summer.

I've been hitting some during the past several weeks, including Shallenberger State Nature Preserve on Sunday afternoon. A short drive down Rt. 33, it's a hidden secret among the popular spots lying among the Hocking Hills.

Shallenberger is like most state preserves that don't lie within state and local parks. It's got a small parking lot and a bulletin board. Go to the bathroom beforehand and print your own map. Then, once you're there, enjoy a remote walk through great forests and rock features.
