Prospects for Detection of Ephemeral Historic Sod Structures Using Geophysical Techniques in Custer County, Nebraska

Sod houses represent one form of ephemeral historic structure that became common to portions of the Great Plains as a result of the Homestead Act of 1862. Since their construction in the late 1800s and early 1900s, sod house and out buildings have either been preserved, allowed to "melt," deliberately removed and put under cultivation. This poster examines the documentation of these structures under various post-occupation conditions through the use of surface level, non-destructive, geophysical techniques. I will report on the 2014 geophysical survey of these structure locations from Custer County, Nebraska.

草皮屋（sod houses）是一类临时性历史建筑，因1862年《宅地法》（Homestead Act of 1862）的推行，在美国大平原（Great Plains）部分区域广为流行。自19世纪末、20世纪初建造以来，草皮屋及其附属建筑的命运不外乎三种：得到保存、自然消解坍塌，或是被刻意拆除并改造为耕地。本海报通过地表无损地球物理勘探技术（surface level, non-destructive, geophysical techniques），探讨不同废弃后状态下这类建筑的遗存记录情况。本文将报告2014年对内布拉斯加州卡斯特县（Custer County, Nebraska）内相关建筑遗址开展的地球物理勘探成果。
