Northern Exposure - Lunch Room to Crystal King Hall
This route goes into the northern section of the cave. It is fairly easy with only a few sections of steep easily-navigated slopes. The route can be reached from the Orange or Green Routes.
Enter the Yellow Route by descending the crack near Green #12 . Once through the crack the passage widens. Follow the flagging down the slope to Yellow #4. This point is where the Yellow Route completes its loop. Follow the flagging down into the Game Room (Yellow #5). This is a nice flat-floored room with nice size passages going off in all directions.
Follow the flagging or take the direct climb down to next room (Yellow #7). After leaving this room, traverse the large sloping passage to a stoopway. Scramble up through the breakdown to the base of a long slope. At the top of the slope (Yellow #14), a horizontal passageway is reached. Staying on this level, the passage is quickly traversed back to Yellow #4.
Once back at Yellow #4, the route can be followed to the intersection of the Orange Route. Follow the easy horizontal route. After an easy squeeze between two boulders, the route runs into the orange flagging (Orange #3 and 4).
