Me and zhihao..woohoo!



Yellowstone grand canyon waterfalls!


a tree that can live on almost nothing...


ops this bison is not our day trip photo..but we were amazed by this big chunk of flesh able to stand on the steep grasses..and our day trip we saw lots of bison and their poos...they couldnt stop eating and eating and eating...



besides the rapid water that flow into the yellowstone lake...



the temperature we were experience on our day trip...cold isnt it..

















it is labelled black pool when it is so BLUE!
