"Major Geographical Features
The Silver Marches generally includes the lands west of Anauroch, east of the River Surbrin, and north of the River Rauvin, although vast stretches of the forests and mountains within these borders are unsettled wilds.
The Cold Wood: A pine, birch, and spruce forest unmarked by civilized settlers or foresters, the Cold Wood is home to some Uthgardt tribes whose members never cut down living trees. Snow cats, orcs, and ettins roam the wood.
The Moonwood: The large forest north of Silverymoon is blessedly free of orcs and other goblinoids. Unfortunately, this has little to do with the efforts of Silverymoon's rangers and much to do with the fearsome reputation of the lycanthropes who inhabit the forest's northern quarter. Many of these evil lycanthropes are members of the People of the Black Blood, a sect of Malar-worshiping werebeasts who resent the civilizing influence of Silverymoon.
Nether Mountains: Silverymoon may be civilized, but its people will never grow soft as long as they have to contend with the yearly tides of monsters that tire of the hard life in the mountain snows and look to the lowlands for plunder. The pass between Silverymoon and Sundabar is closed about six months of the year by heavy snows.
Rauvin Mountains: Goblin kingdoms and orc warrens infest these mountains. The River Rauvin passes through the peaks in a steep-sided, mist-filled gorge of roaring white water. A perilous trail climbs along the shoulder of the gorge through Dead Orc Pass to the north side of the Rauvin, but most travelers choose to pass around the mountains to the east, since the pass is the home of a particularly strong and aggressive orc tribe."
Further reading says that the geography of TSM is like that of Western Europe.. Here are some nice shots I've found

Feel free to add more.... the reason I'm asking is that I'm playing round with world builder and YATT, and I want to see how good I can get it.
