OK, Northest airport sleuths, just how well do you know your DEAD airports? They may be gone now, but their spirits live on....one night (well, OK, one week) a year. Can you identify all these dearly departed airstrips? The following eight photos show what's left of airports that once were visited by airmen and airplanes, just like you and yours. Some of them may be easy, but I bet a few of them will surely challenge even the most dead-icated abandoned airport sleuth.
For a hint, double-click the bat next to each photo (who seems to be experiencing some gusts on final). 
Dead Airport #1:
We'll warm up with an easy one....

Once the site of a large Naval Air Station, now it's Seattle's Warren G. Magnusun Park (named for the senator who was largely responsible for blocking a plan to keep part of it open as a general aviation field). The army's first round-the-world flight departed from here in 1924, Wiley Post stopped in, and Charles Lindbergh also landed here in the Spirit of St. Louis on his tour around America promoting aviation after his historic solo flight across the Atlantic. Rumors persist that there are various WW II-era and postwar aircraft (I've heard TBM Avengers and large twin-engine amphibians) sitting on the bottom of Lake Washington. One can't help but wonder if the rumors are true and if some of these historic aircraft could ever be salvaged and restored.
Anybody want to finance a recovery mission?
Dead Airport #2:
Once so famous throughout the land, recently departed from this world, now vanished from our charts...soon to be forgotten completely?
Correctly identified first by Venkatesh Gopalakrishnan.
Martha Lake was once a thriving little airport in Snohomish county, with an FBO offering aircraft rentals, flight instruction and hangars. Sitting inside Paine Field's Class Delta, it was increasingly surrounded by development as Snohomish County grew. After a long decline following the owners death, the field was sold off to the county and closed in 2000. A park is planned.
Martha Lake Airport was listed as "Alderwod Manor" (the town name). In early versions of Microsoft's popular Flight Simulator it came up as the default airport by virtue of being the first airport listed alphabetically, and probably became more famous with non-pilots than almost any other general aviation field.
Dead Airport #3:
They say the dead walk among us, and we pass by them every day, never realizing how close they are.
Some dearly departed airports could say the same thing of us....

By all accounts a busy little airfield for many years, remnants of Bellevue Airport's runway (and a helipad) are still clearly visible today, sticking out from the office parks and strip malls imediately north of I-90, just west of I-405. Local pilots fly over this ghost strip every day and never notice.
it's right under so many peoples' noses.
Dead Airport #4:
Though barely a trace may remain of their former corporeal presence, their spirits still remain. In our cities.....
Correctly identified first by Jeff Davis.
First known as Issaquah Sky Ranch before WWII, and later as Issaquah Skyport, this airport sat just to the left of the Y-shaped pond in the photo above, immediately north of I-90 near Lake Sammamish State Park. At one time the bigest flight school operation in the state, the airport was a longtime center for skydiving and soaring activity. Today, Issaquah's Pickering Place shopping center now occupies the land where the airport used to be; no trace of this field remains. For more details about this ghost strip, click here.
There's a lot more noise now.
Dead Airport #5:
In small towns by the roadside....

Also known simply as North Bend Airstrip, this was one of what used to be many state-owned airstrips in the Cascade Mountain passes. Still clearly visible to pilots flying through Snoqualmie Pass, it sits immediately north of I-90 just east of the small town of Tanner, which is a few miles east of North Bend itself. A large truck stop, which used to sit off the east end of the field (visible at the bottom of the photo above) has apparently expanded onto the former airstrip, but much of it is still clear.
Dead Airport #6:
In the forests....

Another lost state-owned airport in another Cascade pass - this one is just east of Steven's Pass. The runway is not the nice paved strip in the photo above (note the round cul-de-sac at the left end - looks like houses will go up soon); the partially overgrown (unpaved) strip just below the new pavement is the old runway. US Highway 2 (through Stevens Pass) can be seen in the photo above just north (above/right) of the new pavement. This strip is only a few miles southwest of Lake Wenatchee State - which is still among the living, at least of this writing. Much of this area is now part of a state park.
Dead Airport #7:
Deep in the valleys....
Correctly identified first by Domenick Venezia.
Yet another lost state-owned airport in another Cascade pass (do I detect a troubling pattern here?). This one is just south of the high-voltage power lines (visible along the top edge of the photo above) that go through Stampede Pass. Incredibly, this airport is still listed on airnav.com, which says the runway is just 400 feet long (and apparently shrinking, as it's eaten away by the river that seems to run through it). There is little flat or clear terrain along this route, and if the state's original purpose for these Cascade Pass strips was to provide a place to put your plane down in a pinch, this would certainly be a good place for one, especially given the fact that a lot of pilots choose to fly through Stampede Pass. Too bad this one is gone!
And over the hills....
