SW from Dinosaur RidgeSW from Dinosaur Ridge

West of Denver rises the hogback, a long north-south running ridgeline of up-thrust rock. The hogback forms a somewhat scenic backdrop for the western suburbs of the Denver metro area. One section of this hogback is known as Dinosaur Ridge. This neat little peak features a scenic, rambling ridgeline and great views of Green Mountain to the east and Mount Morrison to the west. Stunted pines dot the ridge top, but views are plentiful.

As if the pleasant hiking and enjoyable views were not enough, the hogback holds much for those interested in geology, including loose plate-like sheets of shale, as well as sandstone rippled by ancient waters or sculpted by more modern winds. But you figured Dinosaur Ridge got its name somehow. Indeed, this nifty little mountain holds other surprises: Ancient dinosaur tracks and the bones of these long-gone, giant lizards. This would be a dynamite summit for families or out-of-town guests.

Rank & Prominence: Lists of John

*In a nutshell, soft ranked peaks lacks 300 feet of confirmed gain from the saddle with their highest neighbor. However, if their optimistic prominence proves true, they would be ranked peaks. But let’s not get bogged down in the details here.

While Dinosaur Ridge makes for a great outing any time of year, take note that summers could be hot and crowded. This is a great peak to reserve for snow-season days when it’s just too cold and nasty in the high country or when avalanche danger is unreasonable.

Dinosaur Biking!

Dinosaur Ridge is almost certainly the most technically difficult trail in Jefferson County, indeed, the entire Front Range. Expect to see mountain bikers suffering and falling while hiking the area.

Sounds like a serious opportunity for some helmet-cam. Are you volunteering??? -Sarah

Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.
