- Mechanics (from Ancient Greek: μηχανική, mēkhanikḗ, lit. “of machines”) is the area of mathematics and physics concerned with the relationships between force, matter, and motion among physical objects. Forces applied to objects result in displacements or changes of an object’s position relative to its environment.
- Lower Falls, Clark County, Washington (waterfallsnorthwest.com)
While the lower of the two falls on Lacamas Creek - given the colorful name of Lower Falls - isn’t nearly as pronounced as its upstream sibling, the falls are rather unique in that they have a rather massive face. Here Lacamas Creek slides over a long, domed outcrop, cascading a total of about 45 vertical feet in a run of about 225 feet. In low water, the creek splits into several braids as it slides down the face, but in higher water periods the falls take on a whole new character. What photographs fail to illustrate is how long the falls actually are - there is a significant foreshortening factor at play here, cutting off the top 20 vertical feet of the falls. Unfortunately there really isn’t any way to photograph the entire fall from above.
