Ravenna AKA Great Pit Of Carkoon

Vintage Seattle reader Steve Forbes writes in with this fascinating set of 1957 shots as a section of Ravenna Boulevard was nearly swallowed up. I was not aware of this — thanks for bringing it to my attention, Steve. He writes:
The night of Nov. 11, 1957, the largest and most expensive sewer collapse in the U.S. to that date occurred at Ravenna Boulevard between 16th and 17th Avenues NE. The hole was 60 feet deep but the sewer trunk in question is 145 feet below the street. Repairs took two years to complete, including first a sewer bypass through Ravenna Park, then stabilizing the broken trunk with a newly devised grout material and re-boring the tunnel.

It amazes me that there’s this big tunnel down there that almost no one knows about.
I recently learned that in 1976, another house in the same area experienced a sudden 5-foot slump in the basement floor.
