04-Oct-2012 -- Visited 42°N 127°E yesterday, train to Sōngjiānghé (松江河镇), along the way here view of the western flank of Chángbái Mountains, main peak Báitóushān (白头山), 2744 m high dormant volcano, about 3 km from the shore of its crater lake Báitóushān Tiānchí. Tiānchí is the deepest lake in China, the average water depth of 204 meters, the deepest 373 meters. Wandering the streets during the afternoon, contact a travel agent for Chángbáishān-Tiānchí day trips.
7:30 in the morning at the train station in car, one hour to reach the foot of the mountain to start climbing, sit in tour bus traveling 45 minutes later, nearly 1,441 steps to the top of the hill. Despite brilliant blue sky at the foot of the mountain, cold and windy on top, people have to rent coats. I spent half an hour on summit, it's cold, views are not good. GPS display 2.43 km from the CP point.
Head down the mountain on foot to look for the CP. A return bus driver has discouraged travel on foot, said visitors are not allowed to walk down the mountain, perhaps too close to the border, I have no reason to follow his advice.
Visibility is very bad, I walk very carefully. GPS shows the CP on the ridge side, close to the border; for safety reasons, I decide to give up to reach to CP, the GPS shows 1.33 kilometers to the CP
