One reason to go to Lamoille Canyon, if you've never been there, is the excellent scenery. Another reason would be the excellent geology...including geology related to the metamorphic core complex that makes up the Ruby Mountains — along with several, and more than one type, of low-angle faults — and also geology related to the Pleistocene glaciation of the mountains.

beyond the field that happens to be part of an outwash plain.
|Looking into Lamoille Canyon from just before the entrance to the Ruby Dome Ranch (Google Maps location).|
|Another view looking into the first part of Lamoille Canyon,|
this time from the 2nd day.
|At this point, where a falling rock sign appears on the side of the road, the overall U-shaped nature of the glacially carved canyon can be seen.|
The GBR was located at Camp Lamoille (AKA Lion's Camp Lamoille or the Boy Scout Camp), nestled in a flat area along Right Fork Lamoille Creek (or South Fork Lamoille Canyon). Photos of the area shown below are from Days 1 and 2 of the three-day outing.
|Looking south up the South Fork of Lamoille Canyon. Back in the rocky section of the canyon, Ruby Spire and the Wolf's Ear are on the left;|
Mt. Gilbert is on the right.
|This photo is centered on a lateral moraine of South Fork Lamoille Canyon, which blocked the main canyon (to the left) and has been breached by Lamoille Creek.|
|We've arrived in camp. The Wolf's Ear is still visible as the highest jagged knob near the center of the photo.|
|Rapidly changing lighting at Camp Lamoille.|
|Wolf's Ear is on the left (east side of the South Fork canyon). Mt. Gilbert is the tallest peak on the right.|
|Our campsite below the cliffs. You can see in this photo the very minimal spots of snow below Mt. Gilbert, fairly unusual in the Rubys for late September.|
|A closer view of the Wolf's Ear.|
|Looking up the same canyon from one of the trails near the beaver ponds.|
|An even closer view of the Wolf's Ear (dark knob on the left), taken on the stormy second day.|
|Another view of the South Fork of Lamoille Canyon, taken during a downpour featuring multiple hail events and (later) lightning directly overhead.|
