Cycles of Nature Many natural processes occur in cycles. Some cycles are well-understood, such as ocean tides and annual tree-rings. Other cycles are long-standing puzzles, such as banded chert in sedimentary rocks, glaciation, snowshoe hares, voles and shrews, spruce bark beetles, and salmon returns. This course examines a wide variety of natural cycles, with time scales ranging from galactic to geological to seasonal and daily. Emphasis is on appreciating periodicity in nature, with a basic understanding of its varied causes. Field trip includes an all-day boat trip to the Yukon Island - MacDonald Spit – Sadie Cove area.
