The South Rim Road is open to the Visitor Center, but the remainder of the road is closed to allow for cross country skiing and snowshoeing. The North Rim and East Portal Roads are closed for the season.
Pegmatite is abundant throughout the 48 mile canyon, and is found in the form of stripes on the cliffs as well as large bodies. The largest of these are found upstream from East Portal, but some outcrops are surprisingly close to the edge, such as the Kneeling Camel on the north rim of the canyon. Some pegmatites contain spodumene, a mined lithium mineral. Less common minerals found in pegmatite include magnetite (or hematite), beryl, tourmaline and garnet.
