|Events||Battle of Greenfields|
Mount Gram was a mountain of unspecified location.
The location of Mount Gram has never been established but it is generally assumed that it is one of the Misty Mountains: The Tale of Years mentions that in T.A. 2740 "Orcs renew their invasions of Eriador" without specifying from where, but obviously referring to Orcs of the Misty Mountains, since the previous entries mention those. "The goblins of Mount Gram" who invaded the Shire in 2747 obviously are a bunch of them.
This must be the reason why Robert Foster also mentions Gram to be one of the Misty Mountains, although he doesn't cite a specific source or reason to do so. However, as any confirmation lacks, the mountain could be anywhere within the northern Eriador region.
