Home! Sweet Homestead!
Our new exhibit opened in the Flagstaff Gallery on June 7th, celebrating the 150th Anniversary of the Homestead Act. Visitors have been sharing their homesteading stories with us in the gallery, and we will be adding them to this map all summer.
If you have a story to share, add it in the comments section, and we will create a map point for you!

Rose Parade 2012
Hope you all saw Trail Tenders' entry in this year's
Grand Floral Rose Parade!
Thanks to Vickie Leonard, her wonderful helpers, & her mules Jack & John!
Thanks to our volunteers who happily made the 4+ mile walk through downtown Portland!
And thanks to everyone who turned out to cheer us on!
(It's great to have so many supporters over on the "west side"!)

Transit of Venus-you won't see this again for 100+ years!
One Day Before Our Once-in-a-Lifetime Event
by R. G. Rienks
Tomorrow
afternoon, Tuesday, June 5th, 2012, you will have an opportunity to
safely view and photograph the Venus Solar Transit. This event will not
be repeated for 105 years, or until 2117. Come to the Oregon Trail
Interpretive Center and look on the west side of the building for our
selection of telescopes. These are solar research telescopes and will
allow safe views of the Sun. NO OTHER TELESCOPE IS SAFE FOR VIEWING THE
SUN. Be sure to bring your camera as you will be told how you can take
photos of the transit. As Venus passes across the face of the Sun you
will see the planet as a black spot in the telescopes. Perhaps you will
be able to detect the atmosphere of Venus. Will you be able to see it
through our viewing masks? We will find out just how big the planet
appears. The transit begins at 1500 hours or 3:00 PM PDT and we will
stay until closing at 6:00 PM. The Sun will set with Venus in transit. A
variety of hand-outs will help you in your explorations of astronomy.
Thanks to our sponsors, Astronomy Magazine and NASA Goddard Space Flight
Center.
Saturn
remains in Virgo, Mars is 16.5° behind Regulus. The full Moon rises by
9:00 PM, more than 60° behind Saturn. I have been asked to explain the
meaning of these degrees of separation. The degrees relate to the
distance in angle of arc between two objects. To make it easy to gauge
the distance we use our hands and fingers. In simple form, if you make a
fist and hold it at arm’s length, the width from one side to the other
across the knuckles will be about ten degrees. Using your star chart
from www.skymaps.com
(this is a free download) locate the constellation Leo. Next find
Regulus. Mars will be about a fist and a half to the east of Regulus.
Note the red color of Mars - if the clouds allow a view. For one degree
we use the index finger first joint. As the Moon is about half a degree
wide when full you can cover it with your finger, proving the value of
body metrics. Curiously, a ruler marked in centimeters also works. One
centimeter at arms length is roughly one degree of arc.
