Vífilsfell is part of a 10 km long mountain massif, the Bláfjöll, which are directed northeast to southwest. This corresponds well with the other mountain ranges and fissure systems of the region, the Reykjanes peninsula in Southwest Iceland. The subglacial mound even builds an escarpment reaching out the north, where mostly older lava fields are to be found, whereas to the south, younger Aa lavas form a landscape characterized by cragged ridges and fissures, with only some smoother Pahoehoe in between.
