[:ja]クリスティーナ・コッシュ宇宙飛行士がISSから撮影した北米コロラド州、ロッキー山脈のシャーマン山です。シャーマン山の頂上付近にはヒルトップ鉱山の残骸が残されています。
1878年にリードビル近くで大きな銀の鉱脈が発見され、コロラド・シルバーブームが始まりました。1890年のシャーマン銀購入法で銀鉱業が活性化し、その数ヶ月後にはコロラドで最後かつ最大の金の鉱脈がクリップル・クリークで発見されて、金探鉱者の新しい世代を惹き付けました。1893年にシャーマン銀購入法が撤廃され、コロラドの不安定な鉱業と農業が崩壊しましたが、その後は緩りとまた着実に回復していきました。

[Earthview Wonders] No.896: Mt. Sherman, Rocky Mountains🇺🇸
Astronaut Christina Koch captured from ISS Mt. Sherman, Rocky Mountains.
Mt. Sherman is a 4,280m high mountain summit in the Mosquito Range of the Rocky Mountains of North America. The Sherman mine produced over 10 million ounces of silver, mostly between 1968 and 1982, with a value of over $300 million at 2010 prices. The Sherman silver-lead-zinc deposit is hosted in dolomites of the Early Mississippian Leadville Formation. The prominent ruins of the historic buildings and structures of the Hilltop Mine are often visited and photographed by hikers and mountaineers.
The local scenery on the ground is as follows.
