The super volcano and it's great thermal activity such as Geysers and hot springs.

More than 15 active volcanoes and volcanic fields from Canada until the north of California. Classics are St. Helens, Rainier, Shasta, Lesson and Baker.

USA 2013 Mt. Rainier: The glaciers of this volcano are very impressive. For some scales on the south climbing route see the tent in the red circle and a group of hikers with head lights on obove the red arrow. Picture was taken in the dusk.

USA 2013 Mt. Rainier: About the same view with the tent in the red circle and another one beside. Those crevasses are wide and deep. Picture was taken in the morning.

USA 2013 Mt. Rainier: View from the upper part on the south route to the same tents on the glacier as seen before. Near the red circle (tent inside) you can find a group of hikers standing close to it. Mt. Baker is in the fare background. Picture was taken early morning.

Hawaii is a great example for an active Hot Spot. There you can study all occurences at the Kilauea volcano and it's Puu O'o fracture zone.

Kilauea volcano, which overlaps the east flank of the massive Mauna Loa shield volcano, has been Hawaii's most active volcano during historical time. Eruptions of Kilauea are prominent in Polynesian legends; written documentation extending back to only 1820 records frequent summit and flank lava flow eruptions that were interspersed with periods of long-term lava lake activity that lasted until 1924 at Halemaumau crater, within the summit caldera. The 3 x 5 km caldera was formed in several stages about 1500 years ago and during the 18th century; eruptions have also originated from the lengthy East and SW rift zones, which extend to the sea on both sides of the volcano. About 90% of the surface of the basaltic shield volcano is formed of lava flows less than about 1100 years old; 70% of the volcano's surface is younger than 600 years. A long-term eruption from the East rift zone that began in 1983 has produced lava flows covering more than 100 sq km, destroying nearly 200 houses and adding new coastline to the island. (from GVP)
