- 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.

- Voyager 1, 2 (space.skyrocket.de)
The last two spacecraft of NASA’s Mariner series Mariner Jupiter/Saturn A and B, renamed Voyager 1 and 2 were the first in that series to be sent to explore the outer solar system. Preceeded by the Pioneer 10 and 11 missions, Voyager 1 and 2 were to make studies of Jupiter and Saturn, their satellites, and their magnetospheres as well as studies of the interplanetary medium. An option designed into the Voyager 2 trajectory, and ultimately exercised, would direct it toward Uranus and Neptune to perform similar studies.
