Yuma City River Park/Yuma Territorial Prison Historic Trash Dump Site

A historic trash dump site was discovered by the City of Yuma while excavating a handicap access sidewalk for a washroom facility building below the Yuma Territorial Prison State Historic Park and a City River Park. The excavation area is partially on City property and State Land (Arizona State Parks). The area of concern is in a recently excavated cut-bank containing historic trash; large mammal bones (cow), glass, metal, porcelain, and ceramics. Approximately 10-15 artifacts and 50+ bones and fragments were observed. No items were collected. Two archaeological sites have been recorded in the area, AZ X:6: l (ASM): This site basically consists of the Yuma Crossing National Historic Landmark. Site AZ X:6:90 (ASM) consists of a small historic trash dump site found within the Yuma Territorial Prison yard. ADOT surveys conducted in 2000 & 2001 indication concentrations of artifact scatter areas below and around Prison Hill and directly uphill from this historic trash site. Guard rail posts excavated in the 1990s (no site number was given) along the north end of Prison Hill also produced historic materials.尤马市（City of Yuma）在为尤马领地监狱州立历史公园（Yuma Territorial Prison State Historic Park）与城市滨河公园下方的盥洗室设施建筑修建无障碍人行道（handicap access sidewalk）时，发现一处历史垃圾堆置遗址。此次开挖区域部分位于市属土地及亚利桑那州立公园（Arizona State Parks）管辖的州属土地范围内。本次关注区域处于一处新近开挖的切坡（cut-bank）中，其内埋藏有历史垃圾遗存，包含大型哺乳动物骨骼（牛骨）、玻璃制品、金属器、瓷器及陶瓷器。现场共观测到约10至15件遗物（artifact）与50余件骨骼及骨骼碎片，未开展任何物品采集工作。 该区域已记录有两处考古遗址：其一为AZ X:6:1（ASM），其主体为尤马渡口国家历史地标（Yuma Crossing National Historic Landmark）；另一处为AZ X:6:90（ASM），为一处位于尤马领地监狱院内的小型历史垃圾堆置遗址。亚利桑那州交通部（ADOT）于2000年与2001年开展的勘测显示，监狱山（Prison Hill）下方及周边、以及本次发现的历史垃圾堆置遗址正上方的坡地上，存在多片遗物散布集中区。1990年代在监狱山北端开挖的护栏桩（未赋予遗址编号），亦出土了历史遗存。
