I joined Robyn on this hike that she rallied the troops to. It was a led hike organized through Venture Outdoors from the Geology of City Parks series, led by a Carnegie Museum staff member. I like the group, I've met and hashed with one of the few staffers of the organization and was asked if I wanted to be a group leader and organize themed hikes in the area. An interesting proposition, yes, but they are generally voluntary positions. Starting at the highest point in the park, we hiked down through time, stopping for discussion about the outcrops and interesting geologic features we reached. I've studied quite a bit of geology and even took a paleontology course, so the general information on geologic history and fossils of the area presented was nothing new. Information on the area's sedimentation and stratification, as in the exact names, composition and time scales of deposition, was new to me and fascinating. Although the weather was in the low twenties with a light coating of snow, it turned out to be a gorgeous day for a hike with the sun shining warmly upon us through the chilly breeze. Dressing appropriately with non-cotton layers and a light outer shell jacket and cozy wool socks makes hiking in weather like this a delight. Something is not quite right with my GPS record of this hike. A slow leisurely three hour hike with many stops should not equal the 10.7 miles it says the clearly marked and way pointed loop is. We would have had to been moving at a pretty good clip** given the terrain if that were the case. It was more like a four mile hike looking at the scale of the park. I still can't quite tell what went wrong with the device, if it picked up on some part of my drive, which it shouldn't have since it was turned off, who knows. It's something I'll have to pay careful attention to on the next hike. **From my hiking experience I can tell you that hiking over a moderately clear and even path walking at a brisk pace I cover a mile in twenty minutes.
