The main lookout (and all others) on the western side faces rougly east/northeast. However during actual sunrise the canyon will be in deep shadows, and especially the canyon walls you are facing will stay like that for a long time. Not sure if you want to take shots of the canyon in early morning light or of the sunrise itself. Might be difficult to get decent pictures even with HDR.
