Kaiminani loop
Straight up the slopes of Hualalai volcano, brutal grades ! Hualalai is the third youngest and third-most historically active volcano on the Island of Hawai‘i. It is considered to be in the post-shield stage of activity. Six different vents erupted lava between the late 1700s and 1801, two of which generated lava flows that poured into the sea on the west coast of the island. The Keahole Airport, located only 11 km (7 mi) north of Kailua-Kona, is built atop the larger flow. The oldest dated rocks are from about 128,000 years ago and it probably reached an elevation above sea level before 300,000 years ago. The volume of Hualalai is 12,400 km3 (2,975 mi3). Its area is 751 km2 (290 mi2).
