Project Description
The best example in Lanzarote of the presence of numerous erratic blocks, reaching more than 30 m in height. The erratic blocks are described as large rock fragments transported by the lava. In this case, the large blocks come from the partial destruction of one of the flanks of the volcanic building of Volcán de La Corona. This volcano originated in the Upper Pleistocene, around 25 Ka BP. During the eruption, one of the flanks of the volcanic cone collapsed, and the lava gathered in the crater came out the opening dragging blocks of the building. When the lava cooled down, the blocks were left in the lava as it can currently be seen. The blocks moved with the lava flow more than 5 km from the central emissions. The basaltic lava flow has a pahoehoe morphology and an aa evolution.
The main interest of this geosite is related to vulcanology, and the secondary one is geomorphological. It also has great landscape value. These erratic blocks are highly represented as they are abundant and dense.
