I småkupert, godt blottet område med furuskog ligger disse bruddene som dekker et område med diameter på ca. 300 m. Det største av bruddene har et areal på ca. 60 x 10-20 m, og maks. avsenkning 10 m. Betongfester for kran vitner om relativt moderne drift. Et annet brudd litt lenger syd er vannfylt, og således er dybden ukjent. Arealet er imidlertid betydelig, ca. 50 m i diameter. Granitten er lys, homogen og finkornig.
RV 117 går her sørvestover fra Fredrikstad. 4-500 m før den svinger mot nordvest tar en vei av mot SØ mot et hytteområde. Etter et par hundre meter dukker de første bruddene opp.

This work is a report of granite and the granite industry in Norway. It contains a description of the various fields of granite and similar rocks from a scientific as well as from a technical and economical standpoint. The geological occurrence of the various rocks, their chemical and mineralogical composition, are thoruoughlyoughly treated, also the questions of practical interest, as the quality and other technical properties, further the problems of location and conditions for transport, conditions for quarrying and otherquestions of interest in the utilization of the various occurrences of granite. Granite: This chapter consideres first the mineralogical and chemical composition of the granite, and the various types of granite resulting from the varying composition; thereafter the most important structural types and how these are dependent on the geological appearance of the rock. Lakkolites and other froms assumed by granite masses when injected into the crust of the earth, are mentioned; some examples of beautifully formed lakkolites are also mentioned. The question of sheet structure and rift in the granite are of great importance in its utilization, and are of interest both practically and theoretically.
