Much of Brockway Mountain Drive is above 1000 ft.
The west peak tops out at 1339 ft. (at about 200 ft. south of the east end of the top-o-the-mountain loop).

Interesting site, Michigan Highest Named Summits.
Curiously Brockway Mountain is not included, but Mt. Lookout (1335 ft.) is!

None of my maps actually refer to it as Brockway Mountain, but yet the road is <u>Brockway Mountain</u> Drive ??

Thanks all. Interesting stuff.

What I also find curious is that there are three spots in Keweenaw County above 1500, actually above 1530 and none of them are on the list or named- well I guess Mount Horace Greely is named.
