官员周二表示，两名徒步旅行者在黄石国家公园遭一只或多只熊袭击，这是今年以来这家热门旅游景点首次发生熊伤人事件。
美国国家公园管理局表示，应急人员已赶赴袭击现场。袭击于周一下午发生在标志性老忠实间歇泉附近的神秘瀑布步道。公园官员表示，事件正在调查中，未透露两名徒步旅行者的受伤程度。
该公园上一次熊袭人事件发生在去年9月，当时官员称一名29岁徒步旅行者在浊湖步道遭遇“突袭”，伤势严重。
黄石国家公园内上一起熊致人死亡事件发生在2015年，2023年公园西侧曾有一名女子被灰熊杀害。
周一袭击事件发生后，公园内至少五条步道和多个露营地被关闭。公园提醒游客至少与熊保持100码距离、携带防熊喷雾，并留意熊出没的迹象。
“先发现熊，别让熊猝不及防，”公园方面表示，“注意查看新鲜足迹、粪便和觅食点。”
今年3月，科学家在黄石公园发现了2026年第一只灰熊，标志着这些动物的冬眠季即将结束。
“大黄石生态系统”覆盖蒙大拿州、爱达荷州和怀俄明州的部分区域，超出公园直接边界范围，该区域内生活着超过1000只灰熊。
过去五十年来，美国本土的灰熊已从灭绝边缘被拯救回来，但目前它们仍被《濒危物种法》列为受威胁物种。黄石公园官员估计，1975年该区域的灰熊种群数量仅为136只。但在保护措施的助力下，科学家如今认为该种群状况良好，活动范围已超过27000平方英里，栖息地也在不断扩张。

2 hikers injured in bear attack at Yellowstone National Park

Two hikers were attacked by one or more bears at Yellowstone National Park, officials said on Tuesday, marking the first time this year that a bear has injured people at the popular tourist attraction.
The National Park Service said emergency personnel responded to the attack, which occurred on Monday afternoon on the Mystic Falls Trail near the iconic Old Faithful geyser. Park officials said the incident is under investigation and did not reveal the extent of the hikers’ injuries.
The most recent bear attack in the park was in September when officials said a 29-year-old hiker was seriously injured in a “surprise encounter” on the Turbid Lake Trail.
The last human fatality caused by a bear inside Yellowstone National Park occurred in 2015, but a grizzly killed a woman just west of the park in 2023.
After Monday’s attack, at least five trails and multiple campsites at the park were closed. The park reminded visitors to stay at least 100 yards away from bears, carry bear spray and look for possible signs of the animals.
“See the bear before you surprise it,” the park said. “Watch for fresh tracks, scat, and feeding sites.”
In March, scientists spotted the first grizzly bear of 2026 at Yellowstone, marking the beginning of the end of hibernation season for the animals.
There are more than 1,000 grizzlies living across what’s called the “greater Yellowstone ecosystem,” an area covering portions of Montana, Idaho and Wyoming outside of the immediate park boundaries.
Grizzly bears are currently listed as threatened under the Endangered Species Act, after they were brought back from the brink of extinction in the contiguous United States over the last five decades. Yellowstone officials have estimated that the grizzly bear population in the region had dropped to just 136 in 1975. But, thanks to conservation efforts, scientists now consider the population to be doing well, occupying more than 27,000 square miles and expanding their habitats.
