Lots of interesting pics of Mt. Rowe, Gunstock and the Belknap Mountain Recreation area. (even some pics of old bikers at the hill climb!) He also seems to think that Mt. Rowe was pictured on this card.....but....what do I know???

Boardwalk Bluesboy seems to indicate that the Mt. Rowe area was incorporated into the Gunstock Ski area at some point;
"
Gunstock trail map, in 1964, after the first double chair lift to the top of Gunstock had been built. A second double chairlift was added later to run alongside the first. The Rowe Mountain lift and trail complex were still a big part of the overall ski area. In 1986 a major reconstruction project changed the feel of the mountain, quite detrimentally in the opinon of the webmaster. Newer, less challenging trails and shorter lifts were added, while some challenging trails and longer lifts were removed. Notably, the two main double chairlifts to the top of the mountain were both removed and the middle part of the Ramrod trail which had ran underneath the main chairlifts was closed permanently. Much later, a new express quad chairlift to the top of the mountain was added to the left side of the Smith slope."
