This is a ship manifest detailing the 290 Chinese colonists expected to arrive in Cuba aboard the Portuguese ship "Gica." The ship arrived in the port of Havana on March 8, 1864, with 281 of the colonists listed in the ship manifest; seven died during the journey and two remained in Macao.

Four adjacent ranges define the western edge of the Avra and Altar valleys. Even though desert ironwood has dark green, lush foliage much of the year, this tree is almost exclusively a Sonoran Desert species. The same is true of the distribution of saguaros, foothill palo verdes, fishhook barrel cacti, and most of the hundreds of other plants growing here. These rugged ranges also provide natural refuges for a variety of wildlife, including desert bighorn and migratory pollinators. In addition to the biological resources, the area has abundant rock art sites and other archaeological sites.
