Lava delta deltas make attractive sites for building and many villages and towns are located on old lava deltas, such as Garachico on Tenerife. Lava delta Lava deltas, similar to river deltas form wherever sufficient sub-aerial flows of lava enter standing bodies of water. The lava cools and breaks up as it encounters the water, with the resulting fragments filling in the adjacent seabed topography such that the flow can move further offshore sub-aerially. Lava deltas are generally associated with large-scale, effusive type basaltic volcanism. Lava deltas are found mainly associated with volcanic islands, particularly those formed at hotspots as they produce
Lava Lake (Oregon) Lava Lake (Oregon) Lava Lake lies in the Cascade Range about west-southwest of Bend in the U.S. state of Oregon. It is a close neighbor of Little Lava Lake, from which it is separated by solidified lava. Lava Lake is at an elevation of in the Deschutes National Forest. The lake covers to an average depth of . Lava Lake, Little Lava Lake, and other nearby lakes formed after lava flows from Mount Bachelor altered drainage patterns in the area. Solidified lava flows are visible along the shorelines of both lakes, and the volcanic peaks Broken Top and South Sister
