View northeast over Pacific Electric Railroad. Ross Field Balloon School occupies portion on right side of photo over to the railroad tracks. The street marking its northern boundary would be Huntington Drive. The large rectangle just north of this street was Rancho Resevoir, converted into a swimming pool. The principal street marking east boundary of Balloon School property running north to south across this photo about at middle, is Santa Anita Avenue.
View of main Ross Field post headquarters buildings. There are 2 men walking at extreme left of photo. There is a flagpole at left side of photo. There is a car parked in front of post headquarters building.
Military vehicle, probably used to hoist and pull down the observation balloons used at Ross Field. Two men stand at the back, one with his arm raised as a signal. The San Gabriel Mountains can be seen VERY faintly in background. Buildings at the Balloon School can be seen on either side of the truck.
One balloon is secured on left side of photo with approximately 14 men near it. Two men are to the right of this group and are folding what appears to be a large canvas. Three buildings in photo, part of a truck shows to extreme right.
Aerial view south of Balloon School and surrounding part of valley. Large tree-lined street running from center of photo toward lower left edge of photo is Santa Anita. Tree-lined street coming in on right edge of photo about two inches from bottom of photo and intersecting Santa Anita, is Duarte Road. Note wash that at present is just west of Arcadia High School. Rio Hondo Wash runs east to west across middle of photo.
View east shows two balloons aloft over Arcadia and San Gabriel Valley. It is possible that first river up from bottom of photo is Rio Hondo Wash. Some of trees along Santa Anita appear to be in extreme lower right of photo. Tree-lined street showing in extreme lower left of photo is Duarte Road. Second river coming into photo about five inches up from bottom of photo would be San Gabriel River.
View across swimming pool built for the men of Ross Field Balloon School by Anita Baldwin and the community. It was on possibly opening day as there are throngs of guests looking on. This was located where present parking lot of Elks building is located. H.F.Paden in 1978 told us there was also a pool formed of stone in what is now County Park area which was an officers' pool.
One balloon in sky (extreme left) and one balloon on ground with approximately 23 men making it secure. High wire fence in foreground. San Gabriel Mountains form background.
Original description, "Balloon about 30 feet off ground. Balloon has round target-like mark on its side. Under balloon is truck with winch and many men participating in restraining it. Overcast day." Revised description 9/7/2017 by Mark Rosenblum, a local Balloon School historian, identifies it as Rockwell Field in San Diego. It is not Arcadia, but he said the men from the Balloon School at Ross Field in Arcadia, went to San Diego to join in on a public display of the balloons.
