Greyrock Mountain (elevation 7,613 feet) in Larimer County has a highly distinctive profile from Interstate 25 and other eastern vantages. Its steep southern aspect shows dramatically in silhouette as seen from the east. Many admirers of this Ranked Peak do not realize that the mountain’s lines from other directions are also remarkable and highly distinctive. Views of this mountain from various directions are breathtaking, and each provides a special profile dimension of Greyrock.
In June 2010 I published the first in a series of caches about these distinctive directional profiles: "Profiles of Greyrock Mountain--Northeastern View" (GC26C63). The series grew to include 10 caches plus a mystery cache that requires visits to eight of these original caches. The profile caches became popular with serious back-country geocachers and those original caches, plus others I've created in the Greyrock Mountain area since that first one, now comprise about 20 caches.
"AIGUILLE DU GREYROCK”

Directly west of Greyrock Mountain is a tower that rises above the west side of Greyrock Meadow; it is shown on the USGS Poudre Park quadrangle as Point 7456. This highly distinctive feature is referred to by backcountry advocates as the “Aiguille du Greyrock” (Needle of Greyrock). It is a Ranked Peak and is rarely climbed by peak baggers--in part because of its remoteness, but primarily because its precipitous terrain is imposing and suggests that all possible routes to its summit would require technical climbing methods and equipment. There is, however, a route on this "needle's" north side that can be climbed without technical gear if you have appropriate skills and feel comfortable in climbing using small foot and handholds on steep, exposed rock. The final 100 feet of distance to the small summit involves continuous Class 3 and Class 4 climbing terrain. A fall on the Class 4 stretches could be fatal, so only choose to make the climb of the aiguille if you have experience in this type of rock scrambling and have developed comfort in exposed situations. A geocache near the aiguille's summit, GC2KRKN, was published in 2010 and has been logged nine times to the date of this jigsaw's publication.
After you complete the Jigidi puzzle a "completion" message will provide the coordinates of this cache as well as a solid hint for finding it. The hike involves approximately 2 1/2 miles round trip, much of it on trail. The final section is off-trail and requires some bushwhacking. Enjoy the puzzle and the cache-finding experience. As a personal reward, make a climb of the aiguille and nail the cache near its summit!
