From the cache site just to the North you will notice the Superior Canal. Notice the depth of the cut in the ground and the amount of dirt that needed to be removed to build this canal. If you have been through Superior much you may have noticed that at no point do you cross this canal. That’s because the canal runs underneath Superior right down 9th street. The canal goes underground west of town and comes back out about a 1/3 of a mile west of here, just east of the 9th and Washington Street intersection, a distance of ¾ of a mile. You can see the canal if you look east from 9th street at that intersection. The canal lays up to 45 feet underground for much of its route and in the western part goes under Lost Creek.
The aqueduct was built in the mid 1950’s and construction consisted of an open trench in which concrete tubes were placed then joined together and buried. Since most of the houses along 9th Street were already here the trench had to be narrow but deep increasing the chance of collapse. After the completion of the project the street was rebuilt and now no one would even know it’s there.
