Lehner was the first Clovis site I helped excavate.  It was a 1974-75 follow-up excavation of the original 1950s work done by Emil Haury.  I was there in July/August 1974. The day-time temperatures were well into the 100s F (in the shade, which was absent in the dig).  Humidity was in the single digit percentile.  To top this off the sediment we were excavating was a black matte (which absorbed heat) underlain by a white marl (which reflected it).  Our only respite was Ed Lehner's carport or the big mulberry tree in his front yard.  Fortunately, whoever was in charge of the logistical arrangements had set up our accommodations in a hummingbird reserve in Ramsey Canyon in the nearby Huachuka Mountains.  It was a beautiful setting with oak trees shade and a higher cooler altitude that cooled down somewhat at night.  We resided in nice cabins with simple but modern facilities and commuted to the site .  All was well until a massive wild fire burned off most of the mountain, although the reserve was spared.  We arrived at the site in the morning just at first light and worked until just after noon.  Then a long lunch break to avoid the highest heat and another couple of hours work in the evening.  This experience encouraged me to resolve to avoid desert excavations in summer.  You will note that summer work in subsequent years was mainly in Wyoming and Colorado.
