Night Grooves is now the farthest left bolted line on the Zen Garden section of the Lost Angel Wall. Scramble down the gully in between Dream Dome and the Lost Angel wall, and turn left down a 4th class gully to the good ledge left of the large tree, or alternately rap down from the anchors atop Time Traveler (exposed).
This route starts about 15 feet left of tTime Traveler on the obvious ledge. It is a thought provoking slab climb with very thin crimp features and thumb mantels characterizing the main crux moves which come early, and then the route stays consistent until around the fifth bolt with fun moves onto the upper slab with one last bolt before the anchors.
6 bolts to the anchors on top of Time Traveler (a shoulder length sling is helpful for last bolt).
The last bolt on this route can be easily clipped from Time Traveler. On one hand the FA party has altered the character of an existing route. On the other hand, Time Traveler now actually does have two bolts, instead of the original one bolt, so all the incorrect guidebook information stating that the route has two bolts is now correct. Kind of a conundrum.
