Question: The Luna Jacal or Luna's Jacal was the residence of Gilberto Luna, a Mexican pioneer farmer in the area of Texas that would become which U.S. national park located in Western Texas, bordering Mexico?
Context: The gray vireo ("Vireo vicinior") is a small North American passerine bird.  It breeds from the southwestern United States and northern Baja California to western Texas.  It is a migrant, wintering in northwestern Mexico in western Sonora state, and the southern Baja Peninsula in Baja California Sur; it remains all year only in Big Bend National Park in southwest Texas.  It is usually found at altitudes between 400 and in its Mexican breeding grounds.  This vireo frequents dry brush, especially juniper, on the slopes of the southwestern mountains. Gates of the Arctic National Park and Preserve is a U.S. National Park in Alaska.  It is the northernmost national park in the U.S. (the entirety of the park lies north of the Arctic Circle) and the second largest at 8,472,506 acres , slightly larger in area than Belgium.  The park consists primarily of portions of the Brooks Range of mountains.  It was first protected as a U.S. National Monument on December 1, 1978, before becoming a national park and preserve two years later in 1980 upon passage of the Alaska National Interest Lands Conservation Act.  A large part of the park is protected in the Gates of the Arctic Wilderness which covers 7,167,192 acre .  The wilderness area adjoins the Noatak Wilderness Area and together they form the largest contiguous wilderness in the United States. The Luna Jacal or Luna's Jacal was the residence of Gilberto Luna, a Mexican pioneer farmer in the area of Texas that would become Big Bend National Park.  The jacal, an indigenous Tejano dwelling suited to the desert environment, was built about 1890 with a low sandstone and limestone wall about 4 ft , with forked poles set upright into the walls, supporting roof poles.  The house backs up to a large boulder.  A heavier line of poles extends the length of the jacal.  The roof was made of ocotillo branches weighted down with earth and stones, presently replaced with an inappropriate soil-cement roof.  Luna raised a large family at the jacal, peacefully coexisting with otherwise hostile Comanche who used the Alamo Creek area as a war trail.  Luna died there in 1947 at age 108 or 109. Quercus emoryi, the Emory oak, is a species of oak common in Arizona (including inside Saguaro National Park), New Mexico and western Texas (including inside Big Bend National Park), United States, and northern Mexico (Sonora, Chihuahua, Coahuila (including Parque Nacional Maderas del Carmen), Durango, Nuevo León, and San Luis Potosí).  It typically grows in dry hills at moderate altitudes. Luna Lake is located in North Cascades National Park, in the U. S. state of Washington.  Situated 1 mi southwest of Luna Peak which is the tallest mountain in the rugged Picket Range, Luna Lake is a proglacial lake impounded by the moraine of a retreated glacier. Big Bend National Park is a U.S. national park located in Western Texas, bordering Mexico.  It has national significance as the largest protected area of Chihuahuan Desert topography and ecology in the United States.  It contains more than 1,200 species of plants, more than 450 species of birds, 56 species of reptiles, and 75 species of mammals. North Cascades National Park is a U.S. National Park located in the state of Washington.  The park is the largest of the three National Park Service units that comprise the North Cascades National Park Service Complex.  Several national wilderness areas and British Columbia parkland adjoin the National Park.  The park features rugged mountain peaks and protects portions of the North Cascades range. The Emanuel Point Shipwreck Site is a historic site near Pensacola, Florida, United States.  It is located off Emanuel Point.  It has been identified as a galleon of the fleet that carried conquistador Tristan de Luna and his army to La Florida in 1559.  It sank along with most of the fleet during a hurricane that struck the coast shortly after Luna's arrival.  On March 4, 1996, it was added to the U.S. National Register of Historic Places. The Wallace E. Pratt House, also known as Ship On The Desert (sometimes hyphenated), was the residence of Wallace Pratt in what is now Guadalupe Mountains National Park in far western Texas.  Pratt, a petroleum geologist for the Humble Oil & Refining Company, had previously built the Wallace Pratt Lodge in McKittrick Canyon a couple of miles to the north in the Guadalupe Mountains.  Finding the cabin site to be remote and prone to being cut off by flooding, Pratt started construction of a new, modern residence on the east slope of the mountains.  Work on the residence started in 1941.  The house was designed by Long Island architect Newton Bevin, who lived for a time at the site with his wife, and built by contractor Ed Birdsall.  Work was stopped by World War II, but resumed in 1945 and was completed the same year.  In contrast to Pratt's rustic canyon cabin, the house, which Pratt named the Ship On The Desert, is an International Style house with horizontal lines and extensive glazing.  Only 16 ft wide and 110 ft long, the house provides broad views to the east over the plans and the west to the mountains.  The majority of the house is on a single level, with a "captain's bridge" over the dining room giving access to a rooftop terrace.  A detached garage contained a guest bedroom.  Apart from glass, the predominant material was local limestone in several shades. Western Texas College (WTC) is a community college founded in 1971 and located in Snyder in Scurry County, Texas.
