The Poudre River is more than just water; it is a bustling corridor of biodiversity and a testament to the power of restoration. Alongside Larimer County Naturalists, you'll track the progress of both human and beaver-led efforts to protect these sensitive riparian lands. Discover the science and the stories behind the river's ongoing recovery.

Major paving improvements are actively occurring in the Carter Lake and Horsetooth Reservoir areas this month, marking the next phase of a multi-year effort to enhance public access. Since June 2025, Larimer County Natural Resources has partnered with federal highway officials to modernize day-use areas, parking lots, and connecting county roads. Supported by the Colorado Federal Lands Access Program (FLAP), this project ensures smoother travel for visitors to two of the region's most popular outdoor destinations.

What's in a name? A whole lot if your name is Horsetooth Mountain and your profile is part of Fort Collins' City logo. In this 2-hour guided hike, we'll explore the geology, topography, and ecology of one of our area's most iconic natural landmarks. As we hike through the lower part of Horsetooth Mountain Open Space, we'll dig into the science of deep time and the ancient geologic events that shaped the dramatic foothills landscape we see today. We'll also reflect on creation stories passed down through generations by some of the area's earliest residents.

Join Larimer County Naturalists for an up-close exploration of the geology of Devil's Backbone Open Space. Learn more about the area's distinct rock formations that formed hundreds of millions of years ago in ancient environments such as salt flats, floodplains, deserts, alkaline lakes, and gravelly rivers—when North America looked vastly different than it does today. As we hike the Morrison Loop, you'll learn the basics of Earth's history through the colorful rock layers, which have been uplifted by geologic forces to create the Backbone's striking landscape.
