<h3>请注意！这不是一个普通的打了灯光的溶洞，也不是一个普通的人工冰雕乐园，而是世界最神奇的冰洞！它诞生于300万年前的冰河世纪时期。</h3></br><h3> <h3>如梦如幻！进入里面，就像走进了一个美轮美奂的水晶宫！100多米高的五层水晶宫，在这里，只能感叹大自然的神奇造化。<strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></strong></h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>这里，显然是一个神秘的童话世界！脑海里，总闪现出一个冰美人正缓缓向你走来……</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>不用总想着去南极、北极，来到这里，就相当于去了北极和南国！漫步在冰雪的世界里，你一定会产生幻觉，仿佛置身于万里冰封的北国冰雕之地，又好似徜徉在石笋林立的南方溶洞。</h3></br><h3> <h3><strong>它是震惊世界的未解之谜</strong></h3></br><h3>震惊世界！万年冰洞在科学界被称为"地热负异常现象"，其成因一直困扰着专家学者。</h3></br><h3> <strong></strong><strong></strong></h3></br><h3>它的存在至今都是个谜！它不在寒冷的北国，也不在炎热的南方，而在祖国的中部——山西！</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>千百年来一直流传着这个传说：在当地一座深山中，有一个挂满冰锥的冰洞。现在看来，并不是传说。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3><strong>万年冰洞：中华一绝，世界奇观！</strong></h3></br><h3>这个万年冰洞深藏在山西宁武县涔山乡麻地沟村东的山上，海拔2300米。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>它的奇特在于以本地洞外的气候条件论，根本构不成结冰的环境，而洞内一年四季冰柱不化，愈往深处冰愈厚。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>夏天，洞外碧草如茵，鲜花盛开，而洞内寒气逼人，冰笋玉立。这也是世界上迄今为止的永久冻土层以外发现的罕见的大冰洞。</h3></br><h3> <h3><strong>100多米高的五层水晶宫，美爆！</strong></h3></br><h3>万年冰洞距地面有100多米，这里指人可达到的相对深度，下面还有多深，还未探测开发。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>走进这个冰世界，只见洞内的地面、洞顶、洞壁上全是冰。满目的冰柱、冰帘、冰瀑、冰笋、冰花、冰钟、冰床、冰锥、冰葡萄、冰挂、冰兽、冰人.......</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>走进水晶宫，五彩的灯光把冰洞内的一切梦幻了，或玲珑剔透，或晶莹夺目，或姿态婀娜.......</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3><strong>它是水晶宫和北国冰雕的完美结合</strong></h3></br><h3><strong>南方溶洞&北国冰雕的完美融合体，</strong><strong>神奇！</strong></h3></br><h3>这样的冰川奇景在极地才能看到，即便是冬日的冰瀑奇景也没有这样大面积的，也没有这么高深的（可是100多米）。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>寒冷北国的冰雕，炎热南国的溶洞，它们竟然在万年冰洞里完美地合体了！</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3><strong>钻冰洞、踏冰栈、踩冰梯、扶冰栏</strong></h3></br><h3>这个100多米高的万年冰洞，共分为上下五层。进入冰洞，你可以钻冰洞、下冰梯、过冰栈……</h3></br><h3> <h3>每层有平台，可容数十人。洞最宽处直径有20多米，最窄处十几米。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>在冰层最上面，开发了循环路，可使游人上下互不影响。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3><strong>为何万古不化？这是一个谜！</strong></h3></br><h3><strong>300万年来，洞中一直保持在-4℃</strong></h3></br><h3>时间仿佛在这里静止了！300万年了，四季的变幻拿它一点办法都没有，洞中一直保持在-4℃；</h3></br><h3>据说，冬天洞外零下30度左右，而到了洞内，反倒比洞外暖和了许多。</h3></br><h3> <h3>因何制冷，冰层为何万古不化？谜底还未解开！万年冰洞最神奇的地方，就是异于地点炽热、温泉等常见的正常自然现象。相反，像有一个巨大的天然制冷系统，越到深处冰层越厚。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>专家暂时称之为"地热负异常现象"，因为按照一般规律，每深入地层100米，气温将上升0.4℃。而万年冰洞则反其道而行之，越到深处，气温反而越冷，冰层越厚。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3><strong>好神奇！这里的冰竟然有再生功能</strong></h3></br><h3>有学者称，"万年冰洞"并非如人想象的万年不化。</h3></br><h3>其实，它也有融化的时候，只是它有着非常神奇的自我修复机制，有再生功能。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>这个300万年前冰川时代留下的冰原物，洞内万年储冰有多少吨，暂时还无法测算，但是一旦冰量减少，它还会进行自我修复，感觉万古不化。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3><strong>冰火两重天！旁边还有个活火山</strong></h3></br><h3>该"火山"并非科学意义上的"火山"，而是埋藏于地下的煤层，因多种原因造成的自燃现象。在东寨镇前往天池的三岔路口的对面山上，即可看到这种自燃现象。</h3></br><h3> <h3>这个"火山"就在冰洞直线距离几百米的地方，有大量的煤炭自燃，温度高达300摄氏度以上，形成一个天然的"大火炉"，令人称奇！</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3>水火不容，更何况冰与火！然而冰与火隔岭相处，冰洞与火山只隔一山而存，这个现象实属举世罕见。</h3></br><h3> <br data-filtered="filtered"></br></h3></br><h3><strong>巨大的科研价值</strong></h3></br><h3>万年冰洞，积累了大量有关大气、气候、物种的变迁以及人类的诞生和进化等大量信息。作为地球历史的信息沉淀又从未因人为破坏而修改过，因此极具科学价值和观赏价值。</h3></br><h3> <h3>当你去到万年冰洞，你一定会感叹：世界上竟然真的有这样一个晶莹剔透的冰世界！<strong data-filtered="filtered"><strong data-filtered="filtered"><strong data-filtered="filtered"><strong data-filtered="filtered"><strong
