Resident Madison/Wisconsin golf architecture nut weighing in here...
Blackhawk is Madison's west-side equivalent to the east side Maple Bluff (both are located in small suburbs of the city -- Shorewood Hills for Blackhawk, MB for MB). Oddly, both are technically owned by those local muni's, even though they are private clubs in all other ways, and thus local residents of SH and MB have very limited (as in, once or twice a year) playing rights to the courses.
Blackhawk is essentially built on top of, and importantly along the sides of, a small hill that overlooks Lake Mendota. It's a confined property, stuck between a major east-west road through town, an old neighborhood, and the lake, so the course routing is somewhat constrained, and produces a lot of odd-sized holes. Nearly all of the par 4s are under 400 yds, with six of the under 320 yds, and three of those @ 275 yds -- from the back tees. It's ultra-quirky -- the routing over and around and alongside the major hill leads to strange bounces, blind shots, and odd angles for shots, plus the greens for the most part are pretty small. The back nine has back-to-back par 5s (one uphill, one downhill), back-to-back par 4s @ 274 yds, and an uphill, blind, par 3 18th. As Shivas points out, it's one of the great match-play, gambler's paradise courses, because the course lends itself to risky and bold vs. strategic play, as it has a bunch of half-par holes. It's a real golfer's golfers club -- they don't have much in the way of amenities, like a pool or things like that, so it tends to draw a pretty hard-core golf crowd. A lot of Madison city golf tourney winners have come out of Blackhawk.
As for Maple Bluff, it has no apparent ties to Raynor that I've ever found, and I've been looking for awhile (although I don't have access to club records). Howard Tweedie is credited with the original routing and design; the course has been tweaked over the years, with Art Hills having done some work several years ago, but there is no Raynor work there that looks Raynor-esque in any way. The course is short by today's standards, and although it has some quirk as well, it's not as quirky at Blackhawk. It's pretty straightforward, with some very good and very tough greens that the club maintains very well and at good speed. It's THE old-money club in these parts, and PGA pro Jerry Kelly does have a house in MB and does get out there on occasion. (That GChannel episode with him was pretty funny, as part of it featured him chasing a golf ball in the bushes and hacking his way through at least one hole). Kelly's turf is both MB and University Ridge, which has a better practice facility and where his brother-in-law is the UW golf coach. Stricker hangs around Cherokee, run by his father-in-law. All in the family around here....
Bill McBride:
I'd say at least half, if not more, of Cherokee's fairways have marsh bordering both sides. One of the greatest driving rounds of my life came there -- I hit something like 12 of 14 fairways, and the other two were a foot or so in the rough. Which, is distinctly not my game...
