Although he was a "mixed bag", especially by today's standards, I will miss the name Agassiz Rock. As a child in the early 1940's, I remember "bushwhacking" to the top as it was privately owned then and there was no trail. Others must have done so because there was a home-made ladder to the top of the rock.
I also remember hiking on a cold fall day in the dunes of what was then known as Crane's Beach. The Trustees also changed that name to Crane Beach. Not as easy to say as Smith's (no relation), Gale's or Norton's Points, it casts aside the presumed donor's name and is historically incorrect. Maybe the Trustees found a problem with the old man's large Chicago plumbing business in the early part of the 20th century.
