NEW AND HAPPENING TODAY
 
Hooting Owl Lecture Series Tuesday
"Western Artists and Their Influence on The National Parks” by Shirley Spencer
 
Early western exploration of the lands east of the Rocky Mountains revealed a stunning array of ragged mountain ranges, solitary glaciated peaks, incised canyons, enormous trees, and solitary landscapes. Artists were encouraged and employed to depict the new and exciting scenery in watercolor and oil landscapes alerting the American public to the wonders of western lands.  Artists Thomas Ayers, Albert Bierstadt, Thomas Hill, William Keith, Thomas Moran, Chris Jorgensen and later Chiura Obata brought the vibrant impressions of the wild lands of the United States to life in their extraordinary renderings of the natural world. Many of these great paintings became a catalyst for the establishment of National Parks in America. Prior to photography, artists became the eyes of a young nation viewing and depicting the splendor of the western landscapes to an eager public. Lecture participants will view many of these great paintings and discuss the impact that many of these famous artists had on the creation of National Parks and National Monuments that Americans are so rightly proud of and enjoy today.
 
This month's Hooting Owl lecture will take place on Tuesday, July 10th from 6:30 to 7:30 pm at the Sierra Nevada Research Station at 7799 Chilnualna Falls Road in Wawona.  Doors open at 6:00.  (J. Cox)

Art Activity Center
From late June through mid-July,  wetland restoration is occurring at the site of the demolished Art Activity Center to return less than 1 acre of seasonal wetland at the former building site. Crew will be re-shaping the topography of the wetland area and replacing the construction fencing with split rail fencing in July, then planting native plants in autumn.
 
Sentinel Meadow Boardwalk
From late June through mid-July, riverbank restoration is occurring in Sentinel Meadow in a less than 0.25 acre area. Crew will add fences to protect unstable riverbanks, protect vegetation, and define a viewing area of Yosemite Falls in July, then plant native plants in autumn. Portions of boardwalk will be temporarily closed for repair and safety
 
Ahwahnee Meadow
From mid-July to early September, wetland restoration will occur at the southwest corner of Ahwahnee Meadow, to improve hydrology, native plant communities, and wildlife habitat in a less than 5 acre area. Staff will use heavy equipment to remove about 800-1,200 cubic yards of imported fill and contour the site for uninterrupted water flow. Staff will broadcast native seed and mulch in the area in autumn. The project is highly visible to the public and to Aramark staff housing.  (G. Dickman)
