Megan Hutter, author of “Images of America: San Antonio Heights,” discussed her book Saturday at Oakmont San Antonio Heights in Upland. Hutter, who grew up in Alta Loma, spoke before approximately 70 people at the upscale senior care facility, which opened earlier this year.

San Antonio Heights is an unincorporated community immediately north of Upland in San Bernardino County. It covers about 2.6 miles and has a population of 3,300 people, according to the U.S., Census Bureau.

Hutter’s 128-page book, published last year by Arcadia Publishing, presents a rich history San Antonio Heights. The small, affluent community traces its roots to the 1800’s, when retired shipbuilder George Chafee, Jr. founded Ontario Colony.

That tract that included what later became San Antonio Heights.

“I wanted to show that San Antonio Heights has a history all its own,” Hutter said when asked why she wrote the book. “We’re important, too, even though we’re in the shadow of Los Angeles.”

Dr. Depak Sheth, a San Antonio Heights resident, attended Hutter’s talk and said he was fascinated by what he learned.

“I thought it was very interesting,” said Sheth, whose medical practice is in Upland. “I had no idea San Antonio Heights had so much history.”
