 Triangle Hill, as it was named by the American command, is a forested hill that appears as a V shape when seen from the air or on a map. Hill 598 sits at the tip of the V and overlooks the Gimhwa valley less than 2 km (1.2 mi) to the south. From this apex, two ridges extend to the northeast and northwest. The ridge to the northwest is dominated by a hill nicknamed "Pike's Peak". The other connects to a pair of hills that had been dubbed "Jane Russell". A less-prominent ridge, named Sandy, slopes down to the east. Across the valley from Sandy stands Sniper Ridge, located at 38°19 ′ 44 ″ 1 127°29 ′ 7 ″ E.
