The Florissant Formation: A Virtual Tour
Caprock Conglomerate


Close-up of Caprock Conglomerate

The Caprock Conglomerate

The caprock conglomerate consists of granular muddy conglomerate beds. The caprock conglomerate overlies parts of the middle shale unit and protects it by slowing the erosional process. The caprock conglomerate represents debris flow perhaps a lahar that entered the lake. The middle shale unit and caprock conglomerate can be seen in several locations along the trails.
