Autumn comes to the Porcupines

The Escarpment Trail leads up to some of the park's best viewpoints for Lake of the Clouds and the Upper Carp River Valley. And in autumn, when this photo was taken, hikers are treated to a kaleidoscope of foliage as the hardwood forest canopy alights with fall color.

Autumn—specifically the fourth Saturday in September—is also time for National Public Lands Day. Established in 1994, the observance was created by the National Environmental Education Foundation. The main goal of National Public Lands Day is to promote volunteering to help maintain our amazing protected public lands across the nation. It's also a free day for most national and state parks—including Porcupine Mountains Wilderness State Park.

豪猪山到了秋天

悬崖小径通向公园内云湖和鲤鱼河上游河谷的最佳景观。在秋天，当这张照片被拍摄时，徒步旅行者们会看到万花筒般的树叶，因为阔叶林的树冠被秋天的颜色照亮了。

秋天，特别是九月的第四个星期六，也是全国公共土地日的时间。成立于1994，庆祝活动是由国家环境教育基金会创建的。国家公共土地日的主要目标是促进志愿活动，帮助维护全国范围内令人惊叹的受保护公共土地。对于包括豪猪山荒野州立公园在内的大多数国家公园和州立公园来说，这也是一个免费的一天。
