is 126 feet above the water level of Lake Michigan and is moving inland at about 4 feet per year. Beach sand on the dune moves when the prevailing northwest wind exceeds 7 m.p.h.
The movement of Mt. Baldy
is made worse because there is no longer sand collecting at the water's edge to bolster the dune. Beach erosion is taking away more sand from Mt. Baldy
than the waves are bringing in due to the breakwall that was built for the Michigan City Harbor. To try and correct the effect of the breakwall, the U.S. Army Corps of Engineers began feeding the beach in 1974.
Thus far there have been four replenishments of sand to Mt. Baldy
- 1974 fine sand trucked in
- 1983 coarse sand trucked in
- 1996 early summer 35,000 cubic yards slurried in by pipe from the harbor
- 1996 late summer 50,000 cubic yards trucked in
