I always wanted to have a postcard with a snowy view of any of the Hawaii's vulcanoes and I finally got one, thanks to Trisha.

Mauna Kea is a dormant volcano on the island of Hawaii. Standing 4,207 m (13,802 ft) above sea level, its peak is the highest point in the state of Hawaii. Much of the mountain is under water; when measured from its oceanic base, Mauna Kea is over 10,000 m (33,000 ft) tall. Mauna Kea is about a million years old, and has thus passed the most active shield stage of life hundreds of thousands of years ago.
With its high elevation, dry environment, and stable airflow, Mauna Kea's summit is one of the best sites in the world for astronomical observation. Since the creation of an access road in 1964, thirteen telescopes funded by eleven countries have been constructed at the summit. The Mauna Kea Observatories are used for scientific research across the electromagnetic spectrum from visible light to radio, and comprise the largest such facility in the world. - in: wikipedia
