The peak is one of the tallest in the Beatooth Mountains, the ninth tallest in Montana and is in the Absaroka-Beartooth Wilderness of Custer National Forest.  The nearest taller mountain to Mount Peal is Tempest Mountain, 1 mi WNW. Hayford Peak, elevation 9924 ft , is the highest mountain in the Sheep Range of Clark County, Nevada, United States.  It is the seventh-most topographically prominent peak in the state.  The nearest taller mountain is Mount Charleston, 34 mi to the southwest.  In the winter months, there is snow on the peak, which usually lasts until early spring. The Indira Col (altitude 5,764 m ) is a col (mountain pass, also called "La" in the local language) on the Indira Ridge in the Siachen Muztagh in the Karakoram Range.  It is within 3 km of Sia Kangri to the west, the summit of which is the tripoint where territories controlled by India, Pakistan and China meet. Mount Cabuyao (alternatively spelled as Mount Kabuyao) is a mountain in the Philippines located in the municipality of Tuba in the province of Benguet.  Its summit, rising to more than 2,000 meters above sea level, overlooks the city of Baguio.  It is commonly mistaken as Mount Santo Tomas, a taller mountain just beside it. Sia Kangri (7,442 m, 24,370 ft) is a mountain in the Baltoro Muztagh in the Karakoram.  Its summit is the tripoint of territory controlled by India, China and Pakistan where the Actual Ground Position Line between Indian and Pakistani forces meets Chinese-controlled territory.  Territories on all sides are disputed.  The land immediately to the southwest of the peak is claimed by both Pakistan and India and controlled by Pakistan.  The land to the northeast is part of the Trans Karakoram Tract, controlled by China under a 1963 border agreement with Pakistan but claimed by India.  The land to the southeast is claimed by Pakistan and India, but controlled by India, as a part of its Siachen glacier territory.

Liangkang Kangri is 7535 m high.  To the south, a ridge leads to the 7570 m Gangkhar Puensum 2 km to the south-southeast .  Due to the low saddle height of 234 m , Liangkang Kangri is not regarded as an independent mountain.  Westward a ridge leads to the 6680 m high Chumhari Kang.  The Liangkanggletscher on the northwest flank and the Namsanggletscher on the eastern flank of Liangkang Kangri form the headwaters of the Lhobrak Chhu, a source river of Kuri Chhu.  The glacier on the southwest flank belongs to the catchment area of Angde Chhu.
