Yosemite National Park - No Camping Area - Open Data

The no camping area is derived from the Yosemite Superintendents Compendium and Wilderness Management Plan that regulating camping in Yosemite. In general, there is no camping one mile from a public access road and four miles from a trailhead in Tuolumne Meadows, Yosemite Valley, Wawona, Glacier Point and Hetch Hetchy. In addition, the Dana Fork watershed is closed to camping, as are the Dog Lake and Elizabeth Lake Wilderness Zones. The no camping regulations of 100 ft from water and trail were not included in this dataset as there are some exceptions to that depending on the conditions on the ground and would not be appropriate for this dataset. Camping is permitted in designated campgrounds within the no camping area. Those include all the park campgrounds in Yosemite Valley and those outside Yosemite Valley: White Wolf, Crane Flat, Hodgdon Meadow,Tamarack Flat, Yosemite Creek, Porcupine Flat, Tuolumne Meadows, Bridalveil Creek, Wawona and Hetch Hetchy Backpackers Campground. In wilderness areas camping is permitted in backpacker campground in Little Yosemite Valley and all the High Sierra Camps: May Lake, Glen Aulin, Vogelsang, Sunrise, and Merced Lake. The blanket no camping rules do not always correspond to what has been historically enforced by wilderness rangers on the ground. This layer has been altered to reflect that. Some notable as Inspiration Point and Poopenaut Valley. Additionally, some areas are within the four miles from a trailhead, based on historic wilderness enforcement and policy. Camping restrictions in the winter months are reduced and this layer is not representative of the winter camping restrictions. IRMA Data Store Reference

本禁露营区域数据集源自《优胜美地（Yosemite）管理总监纲要》与《荒野管理计划》，二者对优胜美地内的露营活动作出了规范。一般而言，在图奥勒米草甸（Tuolumne Meadows）、优胜美地谷（Yosemite Valley）、瓦沃纳（Wawona）、冰川点（Glacier Point）与赫奇赫奇（Hetch Hetchy）区域内，距公共通行道路1英里范围内、距步道起点4英里范围内均禁止露营。此外，达纳福克流域（Dana Fork watershed）、狗湖（Dog Lake）荒野区与伊丽莎白湖（Elizabeth Lake）荒野区同样禁止露营。本次数据集未纳入“距水源与步道100英尺范围内禁止露营”的规定，因该规则存在诸多基于实地情况的例外情形，不适用于本数据集。禁露营区域内的指定营地仍可开展露营活动，此类营地包括优胜美地谷内的所有公园营地，以及谷外的下述营地：白狼（White Wolf）营地、鹤坪（Crane Flat）营地、霍奇顿草甸（Hodgdon Meadow）营地、塔玛拉克平地（Tamarack Flat）营地、优胜美地溪（Yosemite Creek）营地、豪猪平地（Porcupine Flat）营地、图奥勒米草甸（Tuolumne Meadows）营地、新娘面纱溪（Bridalveil Creek）营地、瓦沃纳（Wawona）营地与赫奇赫奇背包客（Hetch Hetchy Backpackers）营地。在荒野区域内，可在小优胜美地谷（Little Yosemite Valley）的背包客营地以及所有高塞拉营地（High Sierra Camps）开展露营活动，包括梅湖（May Lake）营地、格伦奥林（Glen Aulin）营地、沃格尔桑（Vogelsang）营地、桑赖斯（Sunrise）营地与默塞德湖（Merced Lake）营地。全面禁露营规则并非总能与荒野巡护员实地执行的历史执法规则相一致，本图层已据此作出调整。灵感点（Inspiration Point）与普普诺特谷（Poopenaut Valley）即为典型例外。此外，部分区域虽处于距步道起点4英里范围内，但基于历史荒野执法与相关政策，仍允许开展露营活动。冬季的露营限制有所放宽，本图层无法反映冬季露营的限制要求。数据来源：IRMA数据存储库（IRMA Data Store）。
