Eric was absolutely incredible! He is a professor of geology at one of the local colleges in Colorado Springs, and is truly a wealth of knowledge on the topic. My sister and I are so happy that we came across this tour, it exceeded all of our expectations. Eric took his time on the trails, showed us many examples of different rocks, formations, fossils, and answered all of our questions! He is so kind and passionate about the area, and went above and beyond to ensure we had a great visit. Truly exceptional, thank you Eric!! We would recommend this tour to anyone.
