Human activity may also have contributed to their decline. Most mainland Woolly Mammoths disappeared around 10,000 years ago, although isolated populations survived much longer. The last known Woolly Mammoths lived on Wrangel Island until approximately 4,000 years ago.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan\u003eWhy Are Mammoth Tusks Often Broken and Split?\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eComplete mammoth tusks are much less commonly recovered than fragments. After death, a tusk could remain buried for thousands of years while being exposed to pressure, moisture, mineral changes and repeated freezing and thawing. These processes can create weaknesses and enlarge natural cracks within the dentine.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eRiver systems can cause further fragmentation. As Alaskan rivers erode ancient sediments and permafrost, mammoth remains can become exposed and move through gravel deposits.
