Introduction From traditional fishing communities to wild stretches of shoreline, tidal creeks and rivers, this segment is one where paddlers can steep themselves in “Old Florida.” This is also the only segment where paddlers can follow two scenic rivers for a significant distance: the Crooked and Ochlockonee rivers. The Crooked River is the only area along the trail where paddlers have a good chance of spotting a Florida black bear. Several hundred black bears roam the Tate’s Hell/Apalachicola National Forest area, one of six major black bear havens in the state. Florida black bears are protected under Florida law. Keep food and garbage tightly packed and hanging in a bag from a tree branch at least ten feet off the ground. In paddling the Crooked River paddlers will enjoy a slice of the untrammeled 200,000- plus-acre Tate's Hell State Forest. This scenic route also features Ochlockonee River State Park where there is a full-service campground a short distance from the water. For camping reservations, visit Reserve America or call (800) 326-3521.

Designating the St. Marks River as a Florida Paddling Trail would: • Bring public recognition to the blueway • Permit FDEP, as resources allow, to enter into management, patrol and protection agreements, and into leases if so stipulated in the designation agreement • Encourage FDEP to identify sources of funding for management and restoration needs • Give private landowners some liability protection • Give the blueway additional consideration in certain public land acquisition and grant programs, such as the Florida Communities Trust Land Acquisition Program, the Recreational Trails Grant Program, and the Florida Recreation Development Assistance Program For a blueway to be designated as a Florida Paddling Trail, a government or a not-for-profit entity must agree to manage the blueway and apply for designation. Applications for designation are available from the Florida Department of Environmental Protection’s Office of Greenways and Trail. Launch sites for the St. Marks River are located at Newport Campground and at the St. Marks River Park in the City of St. Marks. Wooden slat dry launches could be installed or unimproved natural launch areas could be designated for canoes and kayaks to help avoid conflicts between paddlers and motor boaters at the paved launch locations.

    www.nature.com/scientificreports OPEN Historically unprecedented Northern Gulf of Mexico hurricane activity from 650 to 1250 CE Jessica R. Rodysill1,2,3*, Jefrey P. Donnelly2, Richard Sullivan2,4, Philip D. Lane2,8, Michael Toomey1,2, Jonathan D. Woodruf5, Andrea D. Hawkes2,6, Dana MacDonald2,5, Nicole d’Entremont2, Kelly McKeon2,5, Elizabeth Wallace2 & Peter J. van Hengstum2,4,7 Hurricane Michael (2018) was the frst Category 5 storm on record to make landfall on the Florida panhandle since at least 1851 CE (Common Era), and it resulted in the loss of 59 lives and $25 billion in damages across the southeastern U.S. This event placed a spotlight on recent intense (exceeding Category 4 or 5 on the Safr-Simpson Hurricane Wind Scale) hurricane landfalls, prompting questions about the natural range in variability of hurricane activity that the instrumental record is too short to address. Of particular interest is determining whether the frequency of recent intense hurricane landfalls in the northern Gulf of Mexico (GOM) is within or outside the natural range of intense hurricane activity prior to 1851 CE. In this study, we identify intense hurricane landfalls in northwest Florida during the past 2000 years based on coarse anomaly event detection from two coastal lacustrine sediment archives. We identifed a historically unprecedented period of heightened storm activity common to four Florida panhandle localities from 650 to 1250 CE and a shift to a relatively quiescent storm climate in the GOM spanning the past six centuries. Our study provides long-term context for events like Hurricane Michael and suggests that the observational period 1851 CE to present may underrepresent the natural range in landfalling hurricane activity.

  • Chapter 11 the Late-Pleistocene Human Settlement of Interior North America: the Role of Physiography and Sea-Level Change
    The Late-Pleistocene Human Settlement of Interior North America: The Role of Physiography and Sea-Level Change 183 Chapter 11 The Late-Pleistocene Human Settlement of Interior North America: The Role of Physiography and Sea-Level Change David G. Anderson1, Thaddeus G. Bissett2, and Stephen J. Yerka3 ABSTRACT The colonization of interior North America during the late Pleistocene, ca. 20k–10k cal yr BP, would have been profoundly shaped by physiographic features early explorers and settlers encountered, such as the location of major river valleys, mountain ranges, deserts, pluvial and periglacial lakes, and ice-sheet margins, and in coastal areas by the dramatic changes in sea level that were occurring. An examination of the rela- tionship between changes in sea level and the extent of the Gulf and Atlantic Coastal Plains in the vicinity of the southeastern United States indicates that, because of the uneven topography of the now submerged continental shelf, sea-level rise or fall does not closely correspond to the area lost or gained. During some periods, notably MWP-1A (Meltwater Pulse 1A), only small areas of the Coastal Plain were lost, while in others, such as during the Younger Dryas and MWP-1B, much larger areas were affected. The widespread appearance of Clovis in the interior of the Southeast, and the apparent reduction or reorganization of im- mediate post-Clovis settlement in the Coastal Plain, and an increase in population—or at least no evidence for reduction—farther into the interior of the region may be related to these changes in sea level. Evaluating these ideas will require much new fieldwork and the collection, compilation, and public dissemination of primary archaeological data among the professional community.
