This design captures the essence of beautiful Tennessee landscape and outdoor recreation. The centerpiece is a curved horizon (fisheye lens) showcasing golden autumn trees, lush green forests, and a winding river - all representing your diverse natural attractions. I've included a small figure paddling on the water to highlight the popular water activities. The flowing script for "Marion County" adds a welcoming, small-town feel, while the bold "TENNESSEE" grounds the location. I've used a warm color palette of orange, green, and aqua/blue to evoke the natural beauty of the area. This versatile logo should work great across all their marketing materials, conveying both the adventure and charm Marion County offers.
