Mount Glennon is one of the nine Hogbacks that are located directly west of Denver. People consider the Hogbacks to be where the Rocky Mountains start, in the Front Range of Colorado. Also, it is conveniently located less than five miles from the famous Red Rocks Park and Amphitheater and from its summit, Mount Morrison appears to be towering over the geological wonder. Also a clear view of Denver can be seen along with its huge suburbs. Civilization has built itself around these Hogbacks but they still stand out and act as a very important landmark in the Front Range. Mount Glennon is no different than the rest of the Hogbacks. While on your way to the summit, you spot very old rock with ripples and many layers can be seen from its saddle with Dinosaur Ridge and Unnamed 6262 (both Hogbacks). The mountain is also marked with many small dinosaur remnants, however they do not compare to the large dinosaur footprints that are found halfway up Dinosaur Ridge. As you drive along US 470, you look directly up Mount Glennon and see that its slope appears to be very easy. Don't be fooled, the mountain contains very dangerous terrain and if you plan on summiting, you must be prepared to climb across some class 2+ pitches, along with the other eight Hogbacks.
From Denver, connect to US 25 and drive south to the intersection and connect to US 285. From, there, pass the intersection for US 470 and head to the town of Morrison. Make your first left or drive into the neighbor hood on the left and approach the mountain from its backside.
