The Poudre River Trail offers visitors the opportunity to visit the majestic Bluffs. The Bluffs geological system is distinctive along the Cache La Poudre's edge. Carved by the river over millions of years, the bluffs today rise majestically from the river bottom to over 200 feet above the waters edge. In some cases the bluffs create vertical cliffs of 50 to 60 feet high before tapering and rising south to their full height. The bluffs have also been carved over the years by continuous erosion due to rain and irrigation runoff. Today, they create a strongly, undulating surface with ravines and arroyos that visually dominate the hillside. The trail also presents a majestic panoramic view of the Rockies, the escarpment created by the Poudre river at the Fox Hills Formation, a view of the Colorado Piedmont formation, and of the river's oxbows. Adjacent to the trail there is also a natural aquifer seepage, which creates a natural artesian well which was used as a water source for nearby residents. The seepage can still be seen today, delineated by a rich growth of plant material. For more information about Weld County or Colorado's Geology visit the Geologic Time Machine.
