[Geysers] Widest Cone-Type Vent

[JEFFREY CROSS]

Which cone-type geyser has the widest vent?

Giant's vent is said to be 5 x 7 feet.

Steamboat's vent could be larger, but I have never heard a reliable estimate of its true size.

I cannot think of a vent wider than 5 x 7 feet for which the eruption is cone-type.

Larger vents certainly exist, but the eruptions from them give fountain-type bursting eruptions.
