Shishapangma: Shishapangma, also called Gosainthān, is the 14th highest mountain in the world at 8027 m above sea level.  It was the last 8,000 metre peak to be climbed, due to its location entirely within Tibet and the restrictions on visits by foreign travelers to the region imposed by authorities of the Government of China and of the Tibet Autonomous Region.

Mount Waddington: Mount Waddington, once known as Mystery Mountain, is the highest peak in the Coast Mountains of British Columbia, Canada.  Although Mount Fairweather and Mount Quincy Adams, which straddle the US border between Alaska and British Columbia are taller, Mount Waddington is the highest peak that lies entirely within British Columbia.  It and the subrange which surround it, known as the Waddington Range, stands at the heart of the Pacific Ranges, a remote and extremely difficult set of mountains and river valleys.

He holds the record for the most total ascents of eight-thousanders, with 30.  These include twenty-one ascents of Mount Everest, five on Cho Oyu, two on Manaslu, and one each on Shishapangma and Lhotse.  In 2009 Tashi was featured in the Discovery Channel series "".

Shastina: Shastina is the highest satellite cone of Mount Shasta, and one of four overlapping volcanic cones which together form the most voluminous stratovolcano in the Cascade Range.  At 12,335 ft , Shastina is taller than Mount Adams and would rank as the third highest volcano in the Cascades behind Mount Rainier and Shasta were it not nestled on the western flank of its higher neighbor.  Shastina has a topographic prominence of over 450 ft above the saddle connecting it with Shasta and easily exceeds the typical mountaineering standard of 300 ft for a peak to qualify as an independent summit, yet most lists of Cascade volcanoes omit it nonetheless.  The name "Shastina" is a diminutive of Shasta.

Mount Osborn: Mount Osborn is the highest point in the Kigluaik Mountains, and also on the Seward Peninsula.  It is approximately 4714 feet high and is located on the north end of the range.
