12 April: On a gorgeous spring day following yesterday’s late afternoon and evening rain, we explored some Mammoth Cave NP hiking trails. The 7.9 miles of our hike was mostly level through an attractive hardwood forest, where several kinds of wildflowers were in bloom. Views of the interesting topography, the Green River valley, and distant ridges were unobstructed because the leaves had only just begun to come out.
13 April: A travel day, from Mammoth Cave in central Kentucky to the Shawnee National Forest in southern Illinois, by way of a bike shop to get Amy’s flat tire replaced. We ate lunch at an excellent visitor center in the Land Between the Lakes National Recreation Area. Originally LBL was called Land Between the Rivers, until the Tennessee and Cumberland rivers were dammed in 1944 and 1964 to create Kentucky and Barkley lakes. Arriving at our campground, we found a nice quiet site and took a short walk along the lakeside path before supper. Crossing a bridge over a small stream, we noticed clusters of baldcypress knees protruding from the stream and near the shoreline of the lake. We had reached the northernmost limit of these ancient and distinctive trees that are so typical of southeastern swamps.
