Yakehashiri Lava Flow:
A Special Natural Monument Designated by the National
This stream of molten lava that has cooled and hardened
originally emitted from the side of Mount Iwate in 1732.
The lava erupted from a point approximately 970 m above sea
level and flowed for a distance of approximately 3 km. It would
attain a maximum width of approximately 1 km at its end point
when finally coming to a still.
With the land beneath it having been smothered in molten
lava ranging anywhere from several centimeters to as many
several meters, the surface area of the lava remains unable to
support the cultivation of tress despite over 200 years having
passed since the eruption. In fact, all that has been able to
sprout forth are species of mosses and lichens. This further
accentuates the bumpy, ripple-like texture of the lava's surface,
which is called "toragata" ("tiger-shaped") due to bearing a
similarity to the spots on a tiger.
On March 29, 1952, the Japanese government designated the
spectacle as a Special Natural Monument bearing exceptional
auto-translate 国家指定的特殊天然宝藏“燃烧的熔岩流”Kyoro 16（1732）从岩手火山中间流出的熔岩是冷硬的。喷口高出海平面970米，熔岩流延伸约3公里，未端接部分最宽处宽约1公里。表层部分覆盖着距离几厘米几米的熔岩，自喷发以来已经超过200年，但它不允许树木生长，只有生发和地衣诞生。它的表面有涟漪等不规则性，所以它看起来像老虎的斑驳，因此它也被称为“虎形”。它于1952年3月29日被指定为特殊的天然宝藏，因其对学术目的特别有价值。 - - 火山
