Gredera del Volcà Montsacopa

Montsacopa Volcano is listed as a preferred Site of Natural Interest in La Garrotxa Volcanic Zone Natural Park and Partial Nature Reserve. The clay pit is a former clay quarry exploited between the 16th century and the 1960s. The set of layers we can observe in the clay pit lend us an insight into what the eruption was like. We can see the layers of lapilli and blocks produced by the Strombolian activity in the first phase, and the much more compacted layers of ash, deposited by the pyroclastic flow of gas and volcanic matter at high temperatures of phreatomagmatic activity in the second phase, which resulted in the circular crater.
