The geysers of Yellowstone are grouped  in basins located in the western half of thepark. These include Norris, West Thumb, Lower, Midway, and Upper geyser basins.The most famous geyser is Old Faithful, which erupts on the average of every 75minutes for up to 5 minutes, shooting a column of steam and hot water as highas 56m(184ft). About38,000 to 45,000 liters ( about 10,000  to 12,000 gallons) of water are expelled ateach eruption. Other geysers include the Giant, with erupts at irregularintervals, throwing out a jet of hot water up to 61 m (200ft) high; and theGiantess which is erupts for more than four hours, about twice a year.Steamboat Geyser, the world‘s tallest geyser, erupts infrequently but as high as166 m (380ft). Riverside Geyser is one of the most dependable and unusual ofthe park‘s geysers. It sends an arching spray of water over the Firehole River everysix to nine hours. Sapphire Geyser, formerly a hot pool, erupted violentlyafter the 1959 earthquake, but gradually become dormant and has not experienceda true eruption since 1972. Other notable geysers include Daisy, Grand, Porkchop,and Great Fountain.

黄石国家公园的间歇泉多集中在公园西半部的盆地，包括诺里斯间歇泉盆地、西拇指间歇泉盆地、上间歇泉盆地、中间歇泉盆地、下间歇泉盆地。最有名的间歇泉是老忠实泉，它平均每75分钟喷发一次，每次持续5分钟。它喷射出来的蒸汽柱和热水高达56米（184英尺）。每次都会喷发出38000升到45000升（10000到12000加仑）的水。其他的间歇泉还有：巨人间歇泉，爆发没有规律，能喷出一股61米（200英尺）高的水流；女巨人间歇泉能喷发四个多小时之久，每年只喷发两次；蒸汽船间歇泉是世界上最高的间歇泉，不经常喷发，一旦喷发其水柱高达116米（380英尺）；河畔间歇泉，是全公园最可靠、最与不同的间歇泉之一，每隔6到9小时，它就会喷发出一道横跨火洞河的弓形水雾；蓝宝石间歇泉从前是一个热水塘，自从1959年地震后开始剧烈喷发，但又开始逐渐沉睡，从1971年起再没有喷发过。其它著名的间歇泉还有雏菊间歇泉、大间歇泉、猪排间歇泉和大喷泉间歇泉。
