454:. Mostly Snæfell was formed under ice cover. In addition to the main mountain, the Snæfell volcanic system has a series of fissures and smaller subglacial eruptive features, oriented in a south-west to north-east direction (27°), almost parallel to the active northern volcanic zone, which is 45 km (28 mi) to its west. The associated fissure swarm, which was not recognised by earlier authors, has now been mapped to be 27 km (17 mi) long.

is consistent with these datings. The magma has been found to have had residence times of between 100,000 to 200,000 years between eruptions, which is much longer than for other
Icelandic volcanoes and means previous suspicions that the volcano might only be dormant, are more likely to be the case.

Upptyppingar subglacial volcano to its west has compositional similarities to Snæfell which helps the argument for a flank zone
