Description |
Geologisk er forekomsten ganske lik Mjåvatn I: Muresteinsproduksjon av en spaltbar, steiltstående lys beige sandstein. Hovedbruddet ligger tett inntil bebyggelse som nok vil være til hinder for videre drift. Bruddet er lite, og med begrensede muligheter for utvidelse. |
Location |
Bruddet ligger på begge sider av veien mellom Øynaheia/Herefoss og Mjåvatn, ca 2 km fra krysset med RV 42. |
