| Description |
| Bergarten er en relativt grovkornet, rødbrun granitt. Gjenværende materiale i bruddet (relativt store blokker) kan tyde på at her er brutt ut blokk til en brygge eller lignende formål. Det er ikke så mange m3 med stein som er fraktet herfra, og ingen synlige tegn på at det for tiden foregår uttak her. |
| Location |
| Bruddet ligger i veikanten, NV for veien mellom Grimstad og Herefoss, og 100 m SV for sydenden av Holvatnet. |
