The Chartroom is located in the basement of Memorial Union and is accessible from both the union (turn right before the DoIt Help Desk and follow the hall) and the lakefront (go up the tunnel, through the shop, and follow the yellow arrows). This is where you will attend Ground School, as well as your Tech B lesson. The Chart Room houses the Outing Club library and a detailed map of Lake Mendota, including the yellow line. The room also serves as an extension of the Hoofer Lounge for large events.
