补充资料：十字蛇
十字蛇
长白山神秘的现象很多很多，其中关于蛇的稀奇 事也数不胜数。
1995年夏，长白由下松花江上游正在修建水电站；修建水电站的同时，一部分工人在修筑一条便道。 当修到一座无名山峰时，发现了许多蛇。奇怪的是，这些蛇的颜色各不相同，有赤橙黄绿青蓝紫七种色。
修路的人很害怕，但经过研究，还是决定按原计划进行，通过“七色蛇”的山峰。这一天，修路大军兵临峰下，又发现了奇迹：有白黄红绿四条蛇尾部相接，组成“十”字，其中白蛇与黄蛇尾部相接，红蛇与绿蛇尾部相接，四条蛇的尾部又对在一起，蛇头朝着东西南北四个方向。
这种奇怪的“十字蛇”现象，使修路人畏惧不前，停工向上级领导做了汇报．一位班长闻讯，将四管炸药点燃，扔在“十字蛇”附近，然后转身疾跑。一声爆炸 之后，“十字蛇”仍然安然无恙，没损伤一根汗毛。这位班长大惊失色，将这些难解之谜如实报告领导。上级领导从保护珍稀动物角度出发，批准了工人们提出的改变路线的要求。不知谁提议，将这座无名蜂起名为 “聚龙蜂”，于是得到附近百姓的认可。
上述“十字蛇”现象，不是神话传说，而是许多修路工人亲眼所见。这里有许多难解之谜。首先蛇的颜色稀奇，白色和黄色蛇很少见，红色蛇更是闻所未闻，四条蛇尾对尾组成“十”字形，十分罕见，原因不明，用四管儿炸药没炸着，则万万不可思议了。
