赤木川の河岸にある社殿のない神社です。社殿のない神社は、南紀熊野にある聖域の特徴のひとつです。熊野層群の厚い砂岩層が崩壊してできた、河岸の巨石群を祀っています。この厚い砂岩層は、前弧海盆に堆積した熊野層群の上部層の砂岩層です。大正末期頃、日足の高倉神社に合祀されました。
It is a shrine without a shrine on the banks of the Akagi River. A shrine without a shrine is one of the characteristics of the sanctuary in Nanki Kumano. It enshrines a group of giant stones on the banks of the river, which was formed by the collapse of the thick sandstone formation of the Kumano Group. This thick sandstone layer is the upper sandstone layer of the Kumano Group deposited in the forearc basin. Around the end of the Taisho era, it was enshrined at Takakura Shrine at Hitari.

2022/01/20(Thu) 19:37 近代鉱業以前のものと思われる抗道口、製錬所跡、鉱滓の堆積場が、尻剣谷左岸に残っています。鉱石製錬に用いられた焼き窯は上下2段10基の計20基が整然と並び、その上流側にも2段4基の焼き窯の跡があります。豊臣秀吉の『天正通宝』に那智の銅が献上されたという記録が、今日に残る最初記録です。
The anti-road entrance, smelter ruins, and slag deposits, which are thought to be before the modern mining industry, remain on the left bank of Shirikendani. The yakimono used for ore smelting is lined up in an orderly manner with 10 units in the upper and lower stages, and there are traces of 4 units in the 2nd stage on the upstream side. The record that Nachi's copper was presented to Toyotomi Hideyoshi's "Tensho Tsuho" is the first record that remains today.

江戸時代後期（1846年）に発生した土石流で犠牲になられた8名の方々を供養している巨礫です。この巨礫自体が、土石流で流下してきた流紋岩（花崗斑岩）です。色川地域では江戸時代中期以降に、8回にわたって発生した土石流災害の記録が残っています。
It is a boulder dedicated to eight people who were sacrificed by the debris flow that occurred in the late Edo period (1846). This boulder itself is rhyolite (granodiorite) that has flowed down due to debris flow. In the Irokawa area, there are records of eight debris flow disasters that have occurred since the middle of the Edo period.

土石流となって流下した流紋岩（花崗斑岩）などの風化コアストーンを積み石に利用して、何段もの棚田が築かれています。棚田が築かれている範囲は、斜面の傾斜が比較的緩やかな熊野層群の分布域です。
Many terraced rice fields have been built using weathered core stones such as rhyolite (granodiorite) that flowed down as a debris flow. The area where the rice terraces are built is the distribution area of the Kumano Group, where the slope is relatively gentle.

古座川弧状岩脈沿いに1946年の昭和南海地震まで自然湧出していた温泉で、四角い井戸状の石組みが残り、足湯のようなかたちで利用されていたと伝えられています。周囲の岩盤は、流紋岩質火砕岩で、「薬師如来」の文字や仏像などが彫られており、古くから湯治場として利用されていたことが伺えます。
It is said that the hot spring was naturally welling up along the Ichimai-iwa arc until the 1946 Showa Nankai earthquake, and the square well-shaped stonework remained and was used like a footbath. The surrounding bedrock is rhyolite pyroclastic rock, and the characters "Yakushi Nyorai" and Buddhist statues are engraved on it, indicating that it has been used as a hot spring resort for a long time.

串本町の津荷川に存在する落差約4mの滝です。河道を変えるために、現在滝を形成している岩盤（熊野層群の泥岩）を掘削した人工の滝です。いつ頃の工事なのか定かではありませんが、遅くとも明治の中頃にはできていたと考えられています。
It is a waterfall with a head of about 4m that exists in the Tsuga River in Kushimoto Town. It is an artificial waterfall made by excavating the bedrock (mudstone of the Kumano Group) that is currently forming the waterfall in order to change the river channel. It is not certain when the construction will be done, but it is believed that it was completed by the middle of the Meiji era at the latest.

砂岩と泥岩が交互に積み重なった砂岩泥岩互層は海溝の扇状地に堆積した地層でタービダイトと呼ばれます。地層の下面には砂や泥を運んだ乱流（混濁流）の向きを示す痕跡（ソールマーク）が見られます。和深の海岸は、紀伊半島の土台をなす牟婁付加体の地層観察に絶好の地点です。
The alternating layers of sandstone and mudstone, which are alternating layers of sandstone and mudstone, are layers deposited in the alluvial fan of the trench and are called turbidite. Traces (sole marks) indicating the direction of turbulent flow (turbidity current) carrying sand and mud can be seen on the lower surface of the stratum. The coast of Wabuka is a great place to observe the strata of the Muro accretionary prism that forms the basis of the Kii Peninsula.

田子浦の波食棚上には、あたかも”さらし首”を並べたように巨礫が泥岩中に散在しているので、この巨礫を含む泥岩層は「サラシ首層」と呼ばれています。大陸斜面にある牟婁付加体が断層沿いに崩壊して、海底土石流として大陸斜面上を流れて底に堆積したものと考えられています。近年は、泥ダイアピル岩体あるいは泥火山の噴出堆積物とする考え方が提案され論争になっています。
On the wave-cutting platform of Tagoura, boulders are scattered in the mudstone as if "bleached necks" were lined up, so the mudstone layer containing these boulders is called "Sarashi neck layer". It is believed that the Muro accretionary prism on the continental slope collapsed along the fault, flowed on the continental slope as a seafloor debris flow, and deposited on the bottom. In recent years, the idea of using mud diapir bodies or mud volcano eruption deposits has been proposed and controversial.

堆積した時代が大きく異なる地層群の関係を不整合と呼びます。ここでは紀伊半島の土台をなす牟婁付加体と、その上に堆積した前弧海盆堆積体の熊野層群の不整合関係が観察できます。牟婁付加体が5000万〜2000万年前に海溝に堆積し、プレート沈み込み運動で陸のプレートに付加し持ち上げられ、その上に形成された前弧海盆に熊野層群が1800万〜1500万年前に堆積し始めるまでの数百万年間のプレート運動がこの不整合に示されています。
The relationship between strata that have been deposited at different times is called inconsistency. Here, we can observe the inconsistent relationship between the Muro accretionary prism, which forms the basis of the Kii Peninsula, and the Kumano Group of the forearc basin deposits deposited on it. The Kumano accretionary prism was deposited in the trench 50 to 20 million years ago, and was added to and lifted from the land plate by the plate subduction movement, and the Kumano Group was 18 to 15 million in the forearc basin formed on it. Millions of years of plate movement before it begins to deposit years ago are shown in this inconsistency.

Due to the influence of the Kuroshio Current, the northernmost table coral ecosystem in the world has been established. In addition to corals, you can also see tropical creatures with records of the northern limit of Japanese distribution. Ramsar Convention Wetlands.

昭和南海地震（1946年）の津波到達の標柱です。山の斜面には津波の到達水位（約7.9ｍ）が示されています。袋付近は津波が高くなる地形的特長があり、次の南海トラフでの巨大地震で想定される浸水深は周辺地域より大きくなっています。
It is a pillar of the arrival of the tsunami of the 1946 Showa Nankai earthquake. The reaching water level of the tsunami (about 7.9m) is shown on the slope of the mountain. The area around the bag has a topographical feature that the tsunami becomes high, and the inundation depth expected by the next huge earthquake in the Nankai Trough is larger than that in the surrounding area.

河口から流出する砂礫は沿岸流によって運ばれ砂州を形成します。潮岬はもともと島でしたが、陸側から沖合いの潮岬（島）に向かって砂州が成長し、やがてつながり陸繋島となりました。砂州の部分をトンボロといいます。この砂州の上に串本の町並みができました。砂州の南端部には弥生時代の笠嶋遺跡があります。
Gravel flowing out of the estuary is carried by coastal currents to form sandbars. Shionomisaki was originally an island, but a sandbar grew from the land side toward the offshore Shionomisaki (island), and eventually became a tied island. The part of the sandbar is called Tombolo. The townscape of Kushimoto was created on this sandbar. At the southern end of the sandbar is the Yayoi period Kasashima ruins.

Two marine terraces develop at Shionomisaki. From the gravel of the coast on the terraces, it can be seen that this flat surface was once a wave-cut platform formed near the sea surface. It was lifted to the current altitude by repeating uplift with each huge earthquake that occurred in the Nankai Trough.

It is an igneous rock body formed by complex magma movements about 14 million years ago. A variety of igneous rocks coexist on the coasts of Naisho and Naviraka. On the coast around the Shionomisaki Lighthouse, you can observe the boundaries of pillow lava, dikes, and igneous rocks made up of magmas with different chemical constituents, which are the products of submarine volcanoes. On the cliff of igneous rock is Shionomisaki Lighthouse and Shionomisaki Shrine. The Shionomisaki Lighthouse is Japan's first Western-style wooden lighthouse that was temporarily lit in 1897 and was fully lit in 1897. It was rebuilt into a stone in 1891 and uses "Utsugi stone" from Kozagawa town. Pillow lava is used for the stone walls of Shionomisaki Shrine.

It is a volcanic rock body consisting of rhyolite and rhyolite pyroclastic rock formed about 14 million years ago on Kii Oshima. Rhyolite lava and intrusive rocks cover rhyolite pyroclastic rocks, and some of the rhyolite pyroclastic rocks have sedimentary structures that flow underwater. The Miocene igneous rocks distributed in Shionomisaki and Kii Oshima are distinguished as Shionomisaki igneous complex rocks because the magma formation process is different from that of Kumano acidic igneous rocks and they also include mafic igneous rocks.

Thick sandstone layers may be sandwiched mainly between mudstone alternating layers, and lithological formations and strata with varying slopes can be seen. The stratum tilts toward the sea on the south side, the slope becomes higher on the north side, and vertical or upside down strata appear on the south side of Tomikura Kadozaki. It can be seen that near the nose of the ear, the strata tilt in opposite directions on the south and north sides, and there is a syncline axis.
