sail to the crib

Last Monday, I decided to have my class sail out to the the Wilson Avenue crib. Sailing to the crib is good practice navigating in large waves -- it also makes the kids more independent and gets them comfortable being further from shore. Getting somewhere on a sailboat is fun, too, instead of just going around buoys.

Accompanying my sailors in a safety boat, the trip also afforded me a close look at a work of historic engineering. Built in early 1900s, the Wilson Avenue crib is part of the massive hydrological infrastructure that gives Chicago its drinking water. (The most famous part of the system is the Sanitary and Shipping Canal, which reversed the flow of the Chicago River in 1900.)

When operation began in 1866, the first crib pulled clean water through pipes from two miles offshore to a water tower at the corner of Michigan and Chicago Avenues. Meant to equalize water pressure, the water tower gained great fame as one of the few structures to survive the Great Chicago Fire in 1871.

Though the original crib is long gone, others, like the Wilson Avenue crib, remain in operation today. These cribs collect lake water and send it ashore to be purified. One of Chicago's chemical purification plants, the Jardine Water Purification Plant, is the largest in the world.

As a place, the crib feels very surreal. In some ways, it's familiar: I see the crib almost every day. At the same time, though, viewing it from the far side -- and from so close -- make being there totally foreign.

Seeing Chicago's skyline from the crib always makes me feel a bit like an astronaut seeing earth from the moon.

Some of my students call the crib "Azkaban," the wizards' prison from Harry Potter. Although the residents weren't prisoners, the cribs were once inhabited by tenders. Today, however, the systems are automated: no one has lived on the structures for decades.

As a waypoint, a historic building, and a place, the crib is fascinating. I always love to sail to the crib.
