As promised, here's a (lengthy) post with the remaining numbers that weren't picked:
7. Willamette Valley
This most-populated region of the state of Oregon is nestled between mountain ranges that surround it on three sides: east, west, and south. Due to this placement, the broad, flat nature of the land, and the fertile soils which result from Ice Age conditions, the Willamette Valley is incredible farm land. So many things can be grown here that it's easier to list the things that you don't see grown here, like corn and hops.
This is the region where I currently live, and two of Oregon's major universities are in the Willamette Valley: Oregon State University (where I am currently attending, on my last year getting my Bachelor's) and the University of Oregon. OSU was founded originally on an agricultural base, and the lands they use are spread throughout the valley. They're very expansive...one of the sites I had to check for an internship this summer took two hours to log on a good day!
Ancient people and First Peoples/Native Americans knew the benefits of the area, and like the Puget Sound, some tribes didn't have to travel far and had more permanent settlements, particularly toward the coast. The Coast Range mountains cause a rainshadow effect yet the Cascades pull a lot of precipitation, so the balance of rainfall is excellent most years. This year's summer has had a lower amount of rainfall than normal, but not drastically so...the climate here is nearly perfect for a wide range of people, and it's no surprise it's so populated.
10. The Gorge
Another place I've driven by countless times but never visited! Famous for it's beauty and amphitheater, people flock to the Columbia River Gorge for many reasons...the most popular being to see popular music artists play at the venue that seats 20,000 people. Unfortunately, as you can see in this picture, too many people have gotten wise to the idea of sitting on the grassy hills outside the outdoor amphitheater to listen to the shows, and ticket sales have plummeted. This year they'll start blocking off those areas--tickets to The Gorge shows aren't as spendy as most other venues and some really big music artists play there, so I'm in support of this for the most part.
I've heard great things about this area, and I do plan to catch a show there someday.
14. Mt. Hood
In some ways Mt. Hood is similar to Mt. Rainier. Located about 50 miles from a big city (Portland), and the same type of feature, a stratovolcano, Mt. Hood is the tallest mountain in Oregon and among the 'loftiest' due to prominence. It's an active volcano but imminent eruptions are not nearly as likely as those possible by Mt. Rainier. However, glacial ice sheets could cause just as much damage.
Mt. Hood is incredibly popular for skiing, hiking, and climbing. Many climbers find Mt. Hood among the most challenging to climb, even the most experienced consider this mountain difficult. This year, at least two climbers of died and a snowboarder died recently when part of a snow-covered ice sheet collapsed beneath him. Several people have also been lost (and found) on Mt. Hood this year.
22. Oregon Coast
The Oregon coast stretches just over 360 miles from north to south along Oregon's west side. A range of mountains runs most of the length as well, forming the Coast Range. Highway 101 runs along this coast and there are many tourist towns and spots to visit along the way. Famous for fantastic geological features, beautiful scenic sites, fishing, and in some areas, oceanic richness, this is really a region you can't miss when visiting the Pacific Northwest. Many educational sites, like Hatfield, provide indispensable opportunities for college students not only in the state, but in the world.
I try to visit every year, and my mother will hopefully be moving there within the next year, to Lincoln City. Newport is a short drive away, and there is a great aquarium there that is a fantastic visit. My favorite part is going through the big tube where fish swim all around you--including sharks!
Four more to go, stay tuned for the last few!
Go for it Sally!!!!!
