Sea-Floor Sunday #60: Hawaiian Archipelago
This installment of Sea-Floor Sunday highlights a place I’ve never been. But, that’s about to change — my wife and I are headed to Hawai’i next week for an actual vacation. I can’t even remember when I’ve had one of those! The images below are from this beautiful bathymetric map from the U.S. Geological Survey, which can be found here (or by clicking on images below).
This is some serious relief — nearly 10,000 m (32,000 ft) from the highest peak on the Big Island to the deep sea floor off to the southeast. As a result of that relief, immense submarine landslide/slump deposits make up much of the flanks of these islands.
For the first part of our trip we are going to spend a few days on the Big Island touring Hawai’i Volcanoes National Park.
For the remainder of the vacation we will be relaxing on Kaua’i, which is one of the oldest volcanic peaks currently emergent (note that “old” here is ~5 million years). I’m pretty excited to do some hiking up in beautiful Waimea Canyon.
We already have the Roadside Geology of Hawaii book, but if anybody has any other tips for geo-attractions on the Big Island and/or Kaua’i feel free to leave in comments.
