Utah Quaternary Volcanic Vents

This data set represents the mapped quaternary volcanic vents in the State of Utah at scales 1:20,000 - 1:100,000. The data were published in "Quaternary Tectonics of Utah" (Hecker, Utah Geological Survey Bulletin 127, 1993).本数据集收录了按1:20000至1:100000比例尺成图的美国犹他州第四纪（Quaternary）火山喷口（volcanic vents）。该数据集发表于《犹他州第四纪构造》（Hecker，《犹他州地质调查局公报》第127号，1993年）。
