Present day submarine canyons are active conduits for the transfer of large volumes of sediment, carbon and pollutants from continents to oceans. However, the evolution of submarine canyons over geological timescales remains poorly understood due to their erosional nature and low preservation potential. The Late Cretaceous Punta Baja Formation represents a well‐preserved submarine canyon‐fill that […]

Submarine canyon-confined overbanks comprise substantial volumes of thin-bedded sediment gravity flow deposits that were either stripped or overspilled from adjacent channels and offer more complete records of canyon evolution than axial deposits. The Punta Baja Formation, Mexico, comprises a rare exhumed canyon fill with kilometer-scale dip and strike exposures that permit detailed documentation by high-resolution
