I'd never played St. Martins until yesterday so I don't have a reference point for all the changes, but Dan M and his crew sure have a fun 9-hole layout.
I'll present pictures of a few features that stood out to my eyes (all photos are 'clickable').
The green on the uphill par 4 1st hole is really neat, very geometric (rectangular) and deep, the back built up I'm guessing maybe 6':
The 3rd green has a false front and is really sloped on the left side.
Approach view:
From over the green:
The 4th hole, a par 4 (289 yards) might tempt the bigger hitter, but there is a significant fall-off left of the fw as the hole starts to bend to the right:
The 5th is a short par 3 across a depression:
The 6th with the uphill approach shot (Mike Cirba used his 40 year old 4-wood and 5-iron to birdie the hole!):
The green on the 8th hole is another of the type I've not really seen quite like before:
The 9th green has another very geometric green, this one very squarish, with a false front. My second shot from this view with a sand wedge hit about 6' past the pin (a middle pin!) and spun back all the way off the green (d'oh!):
View from over the green:
It must be a riot to play St. Martin's with one of the sets of hickories on site.
I have about 40 pictures total in the St. Martins photo album, which is available here:
