- Geology (Wikipedia)
Geology (from Ancient Greek γῆ (gê) ’earth’, and λoγία (-logía) ‘study of, discourse’) is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science.
- Mount Si (summitpost.org)
With an estimated 80,000 to 100,000 visitors each year, Mount Si is arguably the most heavily climbed trail in the entire state of Washington. Mount Si is used by a wide variety of people- hikers, climbers, trad climbers, trail runners, people training to climb Rainier, and even mixed climbers in winter. It is not uncommon to see paragliders who have used Mount Si as a launching pad, either.
