21741--Encountering Difficulties in the Way of C passess in the Embankment at Culebra Cut,
Showing the Tendency of the land to Slide, Panama Canal.
Some 26 slides have already occurred
along the sides of Culebra Cut. Seventeen
of them have covered an acre or more in
space, and the largest has extended over
75 acres. This largest slide occurred to the
north of Contractor's Hill; we can get an
idea of it in view 21738. Altogether some
225 acres of soil have been moved in the
The famous 47 acre Cucaracha slide (de-
scribed in views 21757 and 21743) belongs
to the kind caused by the slipping of a
lighter top-layer of dirt over a harder,
sloping surface. In the picture here dis-
played an impression of the composition of
the surface material is easily obtained. The
large crevasses in the soil in the foreground
forebodes more sliding at this point in the
future. The observer is near the crest of
the side-slope of the canal, the smoke in the
distance arising from an engine some dis-
tance below at the bottom of the canal. A
slide of this kind is glacial in its action, and
the only remedy seems to be to excavate to
an angle that will not allow any further
sliding of the surface soil.
