  Blue Funnel Spring
Feature Type: Hot Spring
Geyser/Spring Type:

West Thumb Geyser Basin
Lower Group - West Thumb

[The description of Blue Funnel was provided by Steve Gryc.]

Although there has been occasional and dramatic geyser activity at West Thumb, eruptions are rare occurrences. There are, however, a large number of beautifully-colored hot pools in West Thumb's central basin, making any visit to this unique area a rewarding one. Blue Funnel Spring is one of the larger pools and one of the most striking because of its circular rim and pastel blue color which intensifies as the pool deepens towards its central vent. The hottest pools are the bluest since colorful cyanobacteria that live in cooler springs change the color of those springs.

Blue Funnel Spring is located about 280 feet southeast of Twin Geyer.
