Patrick Ganly (1809–1899) was an Irish geologist, surveyor, civil engineer, cartographer and valuator during Griffith's Survey. He was the first person to discover and describe the usage of cross-bedding in geological stratification to show the 'way up' of rock layers, a discovery overlooked until its independent rediscovery over 70 years later.
