caption_attribution_description: English: Irish geologist Patrick Ganly's sketch of rocks on the shoreline at Coosnagloor, near Mount Eagle on the Dingle peninsula, Co.Kerry, Ireland. The top part of the sketch shows a tightly-folded syncline: north to south the rocks get younger until the bedding is inverted. The bottom part details the cross-stratification which helped to indicate the original 'way up' of the rock.
context_page_description: Patrick Ganly was an Irish geologist, surveyor, 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.
context_section_description: Ganly was born in the Rotunda Hospital, Dublin, on 15 October 1809 to Ann and Patrick Ganly. His father was a bricklayer. In 1827 he joined Richard Griffith's boundary survey of Ireland, which had begun two years earlier as a precursor to the first Ordnance Survey of Ireland. He was to work a number of years with Griffith as his boss. Between 1830 and 1832 he worked directly for the Ordnance Survey.
  In 1841 he began study through Trinity College, Dublin, gaining a BA in 1849.
  Griffith became Commissioner of Valuation and Ganly worked under him in his role as a valuator. From 1846–9 during the great famine years, Ganly was engaged in famine relief under the auspices of the Board of Works, of which Griffith had become chairman. He returned to valuation work in 1853, by which time he had married Mary Elizabeth (Eliza) [maiden name unknown]. He was made redundant from valuation work in 1860. It has been suggested that he may have worked in the US in the early 1850s and worked as a civil engineer in Ireland after 1860.
