Glacial Strata 1962

"Glacial Strata" is an abstract black and white lithograph by John Henry Rock, created in 1962. The artwork depicts a series of layered, gestural marks that evoke a sense of movement and depth. The artist's use of heavy black ink against a lighter background creates a dramatic contrast, highlighting the fluidity and dynamism of the composition. Rock's work is often characterized by its expressive quality, and "Glacial Strata" is a prime example of his ability to convey emotion through abstract forms.
