点评:We went to the Midway Geyser Basin pretty early in the day, so the Grand Prismatic Spring was quite steamy and hard to see and photograph from the ground level. We are older, and didn’t feel able to take the long trail to the observation point. Still the colors were beautiful, and we enjoyed the time we spent there. We noticed lots of other interesting things, such as the multi-colored algaes in the runoff waters. This pool has been one of my favorite features since I was a child, so I was somewhat disappointed that the boardwalk did not go clear around the pool like it did when we had come many years ago. I suppose this is because of safety issues. The huge Excelsior Geyser crater was also quite covered with steam, although I’ve never seen it not steamy. The Firehole River is beautiful along this basin, and the runoff coming down into the river is host to beautiful cascades coated with the heat-loving micro-organisms. The walk around the basin is easy, and all boardwalk.
翻译:我们一大早就去了中途间歇泉盆地,所以大棱镜温泉蒸汽弥漫,从地面上很难看清和拍照。我们年纪大了,感觉走很长的步道去观景台不太方便。不过,那里的色彩依然很美,我们也很享受在那里的时光。我们还注意到了很多其他有趣的东西,比如径流水中五彩斑斓的藻类。这个水池是我从小就最喜欢的地方之一,所以有点失望的是,木栈道没有像我们多年前来时那样环绕整个水池。我想这可能是出于安全考虑。巨大的埃克塞尔西奥间歇泉火山口也蒸汽弥漫,虽然我从未见过它不冒蒸汽的样子。火洞河沿着这个盆地蜿蜒流淌,景色优美,流入河中的径流形成了美丽的瀑布,瀑布上覆盖着喜热的微生物。环绕盆地的步道很轻松,全程都是木栈道。
