Krepost (fortress)

Krepost (fortress) is the large geyser on the right bank of Geyzernaya river, across from Shchel geyser. Untill the 2007 slide it considered as a pulsating spring, although some observers witnessed its eruptions. After landslide-dammed lake was formed, Krepost changed its cycle and started working as a geyser with a 3 meter-high fountain.

As Krepost was a relatively unknown spring, when new geyser appeared it was given new names, like Mladenets (baby) etc. However, later it was established that the geyser was in fact a well known Krepost spring.

It's worth noting that this spring is known under one other name — Chaynyy (tea). Previously helicopters used to land on the right bank of Geysernaya river, right across the Velikan geyser and visitors took hot water from the spring to make tea.

Down the slope below Krepost there is a tiny geyser called Pyatiminutka (five minutes). Its working cycle is about 5 minutes. Water splashes up to 10 cm and small steam column are easy to see from the Shchel geyser observation deck.
