We got a flat tire by Summit Lake 7000 feet above the sea level. Tom put the spare on. It was still too chilly to swim. There were three kinds of volcanoes in the park: dome, shield, and cinder cone. Two gray ones were looming in the distance. One of them erupted in 1914. Similarly to Yellowstone, the park had hydro thermal features such as bubbling mud pots, steaming fumaroles, and boiling water.
