Silver Beach in St. Joseph was crowded at lunchtime on Saturday when we passed through (more pictures at hshipman).
St. Joseph is on the southeastern shore of Lake Michigan, at the mouth of the St. Joseph River. As at nearby South Haven and New Buffalo (and Michigan City, in Indiana), waves and longshore transport are from north to south, building up sand on the north side of the river mouth jetties. This also used to happen on other side of the lake, at the mouth of the Chicago River.
Geologically, this sand is destined for the south end of the lake, where it will be blown inland to bury 19th century steel mills and freeways under hundred-foot tall dunes.
