ここを北端点とし、もう片方の南端点を結ぶ直線を「那須基線」と呼んでおり、明治8年（1875）、近代国家を目指した明治新政府（内務省地理寮）が、「関八州大三角測量」として各三角点の位置を決定し、地図作りを進めていくために設置しました。明治17年（1884）に陸軍省参謀本部に測量事業が移管されたことに伴い、全国三角測量の基線として採用されずにその役割は失われ、荒れるままの状態が続いていましたが、平成11年（1999）に土地所有者から南端点の石室一式の寄付を受け、国土地理院の協力を得て発掘調査を行い、平成12年（2000）に復元。地上は大谷石3段積みの石室と芦野石の蓋、地下は大谷石4段積、最下部に基礎コンクリートが打設されています。
平成30年（2018）に那須野が原開拓に係る日本遺産の構成文化財の一つとして認定されており、日本近代測量発祥の地に位置付けられる貴重な文化財です。那須野が原開拓における道水路整備の礎ともなりました。

都道府県魅力度ランキング2020最下位の栃木県ですが、ジオキャッシングではとても魅力的な県です。旧栃木県と宇都宮県が合併し栃木県が誕生した6月15日を記念して、2021年の県民の日に栃木にゆかりのあるジオキャッシャーが募りキャッシュを公開しました。

The straight line connecting this point as the northern end point and the other southern end point is called the "Nasu base line," and it was established in 1875 by the new Meiji government (Geographical Dormitory of the Ministry of the Interior), which aimed to create a modern nation, to determine the location of each triangular point as the "Great Triangular Survey of Kanhachi-shu" and to promote map making. With the transfer of the surveying project to the General Staff of the Ministry of the Army in 1884, it was not adopted as a baseline for the national triangulation and lost its role, eventually remaining in a state of disrepair.
In 1999, the landowner donated a set of stone chambers at the southern end point, and with the cooperation of the Geospatial Information Authority of Japan, excavation was carried out and the chambers were restored in 2000. Above ground, the stone chamber is made of three layers of Oya stone and a lid made of Ashino stone; below ground, the stone chamber is made of four layers of Oya stone, and the foundation concrete was poured at the bottom.
It was recognized as one of the constituent cultural properties of the Japanese Heritage related to the development of Nasunogahara in 2018, and together with the northern end point of Nasushiobara City, it is a valuable cultural property positioned as the birthplace of modern surveying in Japan, and also became the foundation for the subsequent development of the road channel in the development of Nasunogahara.
The cache is located at a bearing of 154.7 degrees and a distance of xxxxx.310589 meters from indicated coordinate.
Please take the longest straight road in Honshu, the "Rice Line (Tatemichi)," which leads from here to the cache.
