补充资料:野牛沟景区
野牛沟靠近大渡河谷,因很多年以前沟内野牛(牛羚)成群而得名。近几年,由于退耕还林、生态保护,沟内又发现野牛行踪,有时牧民在半夜还听到其群体迁徙的声音,次日见其走过的带刺灌木丛像推土机推过一样被踏平。由于野生生态保持完好,当地的家牦牛也体形庞大,威武雄壮。
进野牛沟,一般先坐车到金汤捧塔乡,然后骑马翻越海拔4200米的黑卡梁子。黑卡梁子陡峭异常,坡度达六七十度,原始森林遮天蔽日,骑马穿越十分刺激。翻过黑卡梁子,便来到沟内的银场坪,地势一下变得舒缓平坦。一往沟里走,只见一个个大草坪连着一片片灌木林,沟两边又是茂密的原始森林,再往上则是险峻的寸草不生的滑石山。
令人惊喜的是,原始森林中有大片千年古柏,苍劲挺拔,为全国仅存的原始纯岷江柏树林,最大的三人才能合抱,储积量近2000亩!
