'''May 18 1143 PDT:''' After slowing ascent, balloon reached maximum altitude at 4430m over (37.3780, -121.0420). Balloon then began to descend. While it was not clear at the time why ascent stopped, it is apparent in retrospect that the trajectory had entered areas of inclement weather, and downdrafts and/or rain were pushing the balloon downward.

'''May 19 1530 PDT:''' Unbeknownst to anyone at the time, balloon resumed flight, presumably due to solar heating and drying.
'''May 19 2110 PDT:''' Balloon appeared to land in Yosemite NP, in the vicinity of Vogelsang Peak and Bernice Lake, well above the tree and snow line. Due to noisy RockBlock coordinates, it is impossible to ascertain a precise location, nor to rule out further movement down the slopes overnight.
