Geyser
Yellowstone is the largest geyser locale, containing thousands of hot springs, and approximately 300 to 500 geysers. It is home to half of the world's total number of geysers in its nine geyser basins. It is located mostly in Wyoming, USA, with small portions in Montana and Idaho. Yellowstone includes the world's tallest active geyser (Steamboat Geyser in Norris Geyser Basin), as well as the renowned Old Faithful Geyser, Beehive Geyser, Giantess Geyser, Lion Geyser, Plume Geyser, Aurum Geyser, Castle Geyser, Sawmill Geyser, Grand Geyser, Oblong Geyser, Giant Geyser, Daisy Geyser, Grotto Geyser, the Fan & Mortar Geysers, & the Riverside Geyser, all in the Upper Geyser Basin which alone contains nearly 180 geysers.
Glacier Bay Basin
The Johns Hopkins Inlet is a stunning long fjord, which has several tide water glaciers. The Lamplugh Glacier is about away from the inlet and further inside is the Johns Hopkins Glacier, which is now the largest tidewater glacier in Glacier Bay and adjacent to it is the Gilman Glacier followed by the Hoonah Glacier further up. All these glaciers are tidewater glaciers. Ice blocks float in the inlet and it is quite hazardous for boating or kayaking; both activities have to be done with great caution. Johns Hopkins Inlet is closed to boats in May and June in order to protect unweaned harbor seal pups.
