Black Mountain - The Annual Crab Spider-a-thon

Image
Goldenrod crab spider ( Misumena vatia ) All photos by my beautiful wife, Kelli Lewis-Sutherland. My wife and her best friend, Laurel Abernathy have an annual tradition of visiting the Black Mountain segment of the Cumberland Trail yearly in late August or early September so that they can photograph crab spiders. Many years ago they discovered that the swaths of Maryland golden-aster ( Chrysopsis mariana ) growing alongside the trail there are also home to the adorable goldenrod crab spider ( Misumena vatia ). Approximately one in ten of the flowers has a little white or yellow spider hiding and waiting for its next meal. Ghost pipe ( Monotropa uniflora ) We were guaranteed to get our best photos yet, because we now have a Canon EF100mm f/2.8L macro lens and a ring flash. For a little less than a year, we've been experimenting and learning from this combination and have taken lots of pretty decent macros of tiny critters and flowers. We met up with Laurel and her daught...

Tennessee Wildflowers Through the Eyes of a Geographer

Image
Every spring my photographic activity emerges from its winter slumber and I begin re-learning everything I once knew about wildflowers again. I love this time of year when I can start wearing shorts again, and see the familiar wildflowers return to our roadsides and hollers. While I thoroughly enjoy capturing the beauty of wildflowers, I also like to think about how they ended up in their current location. As a practitioner of Geographic Information Systems (GIS), I find this question particularly intriguing. I provide this not as an empirical study, but rather a casual conversation to introduce readers to GIS concepts as related to wildflowers. The locations where I find my favorite wildflowers share a few common traits: steep slopes facing different directions (known as "aspect" in GIS) and intermittent water sources resulting from nested water tables. By seeking out these characteristics, I am more likely to find ideal habitats for wildflowers. Usin...

Standing Stone State Park and State Forest

Image
For the purpose of this blog post I will be treating Standing Stone State Park and Standing Stone State Forest as a single entity. However, they are distinct, and are managed by different entities with different objectives. Both the State Park and State Forest are located entirely within Overton County, Tennessee about 10 miles northwest of the city of Livingston. Fullscreen map. Standing Stone State Park Standing Stone State Park is approximately 1000 acres surrounding Standing Stone Lake. It is itself surrounded by 8000 acres of State Forest of the same name. The park is a celebration of the efforts of the Civilian Conservation Corp (CCC). The large earthwork dam is made of hewn sandstone. Being a State Park, this area is managed for recreation. Camping there is popular at their rustic cabins. Most people come for hiking trails, fishing, and for paddle boats or kayaking on the small lake. Standing Stone State Forest There seems to be a degree of confusion as to the mea...

Window Cliffs State Natural Area

Image
Geography Window Cliffs State Natural Area is located on the Eastern Highland Rim of Tennessee . It is a few miles south of Cookeville, and within Putnam County. It is within the Upper Cumberland region of Tennessee, and within Middle Tennessee. Cane Creek flows through the designated natural area before its confluence with the Falling Water River at Center Hill Lake. Botany In the valley alongside Cane Creek one can find abundant flowering patches of phacelia, phlox, and trilliums. Along the rocky ledges and cliffs watch for bright red flowers of columbine. In a few places you'll also see usnea clinging to dead trees and be reminded of Spanish moss. Geology Cliffs of Fort Payne Limestone atop steep slopes of Chattanooga Shale are the obvious geology throughout the park. The base of the valleys is Catheys-Leipers Limestone, but doesn't play a large roll in the story that one sees at the Window Cliffs. In the above recreation of a map made by Hugh Mill...
