Mauna Kea – Southern Slope 
One of the best adventures we had on the Big Island of Hawaii was to book a Mauna Kea sunset tour. The tour took us in four wheel drive vans to the summit to watch the sun set and learn about the observatories, geology, ecology and spirituality of Mauna Kea.
Mauna Kea is a dormant volcano with its summit is at 13,796 ft above sea level
This picture was taken above the Onizuka Center for International Astronomy Visitor Information Station. You can see it at the bottom right hand corner of this picture. The station is at 9,300 feet above sea level and our tour group stopped there briefly to acclimate to the altitude and look through some solar telescopes. We stopped again at approximately 10,300 feet to take some pictures. Here you can see a number of cinder cones. And yes, those are clouds. Some of the other pictures show even more dramatic views of the cloud layer as seen from above.
