- Twin Falls, Clark County, Washington (waterfallsnorthwest.com)
The larger and upper of the two major waterfalls on Big Tree Creek is a scenic fine-lined plunge which leaps a clean 66 feet over an undercut basalt ledge, dropping into a surprisingly significant canyon set amid otherwise unassuming timber land. During periods of heavier flow, the falls spread out across a significantly broader expanse of the cliff, potentially tripling in breadth, but still retaining a well defined classic “plunge” form. Contrary to its name, there does not seem to be a “twin” to the plunge currently - the one time second segment has long since been plugged up. Perhaps a flood will unplug it some day.
- Feldspar (Wikipedia)
Feldspar (/ˈfɛl(d)ˌspɑːr/ FEL(D)-spar; sometimes spelled felspar) is a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth’s crust, and 41% of the Earth’s continental crust by weight.
