• Mount Leckie is a roughly circular outcrop about east of Martin Massif. It was visited by the ANARE southern party, and was named for Squadron Leader D.W. Leckie, Royal Australian Air Force, who commanded the RAAF Antarctic Flight at Mawson Station, 1956.
• Mount Lied is a prominent pyramidal peak about east-northeast of Mount Mervyn.. It was sighted by the ANARE southern party lin 1956 and named for Nils T. Lied, a weather observer at Mawson Station in 1956 and at Davis Station in 1957.
• Mount McCarthy is the easternmost peak, high, of the Porthos Range. It was first visited by the ANARE southern party in 1956, and was named by the ANCA for James W. McCarthy, senior meteorologist and second in charge at Mawson Station in 1956.
• Mount Mervyn is a very sharp peak standing south of the main body of the Porthos Range, about south of Mount Kirkby. It was sighted in December 1956 by the ANARE southern party and named for Mervyn Christensen, a weather observer at Mawson Station in 1956.
• Mount Pollard is a partly snow-covered mountain just south of Corry Massif and 3 nautical miles west of Crohn Massif. Mapped from ANARE surveys and air photos, 1956–65. It was named by ANCA for J.R. Pollard, ionosphere physicist at Wilkes Station, 1964.
• Mount Small is a partly snow-covered peak standing 2 nautical miles southwest of Crohn Massif. It was mapped from ANARE surveys and air photos, 1956–65. It was named by ANCA for G.R. Small, geophysicist at Wilkes Station, 1964.
• Mount Tarr is a mountain 1.5 miles east-southeast of Mount Creighton. It was plotted from ANARE air photos of 1965. It was named by ANCA for F. Tarr, aircraft engineer with the ANARE Prince Charles Mountains survey party in 1969.
