New Hampshire

 was a state in the New England region of the United States of America. The fourth Doctor once took Leela there to allow her to spend time with Native Americans. However, he got the time co-ordinates wrong, and they ended up in a New Hampshire that was experiencing a blizzard sometime close to the turn of the 21st century. After finding some shelter from the blizzard, the Doctor and Leela got embroiled in an adventure that centered on Melvin Village, a touristy hamlet on the shores of Lake Winnipesaukee.

Some of the known features of New Hampshire included Mount Washington, the state's highest peak, and a cog railway that serviced the observatory atop Mount Washington. Pease Air Force Base was also located in the state. Its road transport needs were assisted by I-93. (PDA: Drift)
