The boy who left the streets of Long Beach for the flowing rivers and dark canyons of the San Gabriel Mountains and who, as an adult, led millions down a similar path of discovery through his 26 hiking guides and historical books has died.

Wilderness author and local historian John W. Robinson passed away in his sleep on April 24 at the age of 88 — a loss to hiking enthusiasts and naturalists tempered only by the wealth of material he left behind on Southern California’s mountain ranges.

‘Trails of Angeles’ a favorite

Robinson, a Fullerton resident, was perhaps best known for his book “Trails of the Angeles: 100 Hikes in the San Gabriels,” published in 1971 and now in its ninth edition after selling more than 100,000 copies.

The soft-covered, deceptively simple guide to Angeles National Forest hikes that mixes practical pointers with personal anecdotes and voices from historical characters is still hauled up switchbacks and across rivers by hikers, nature lovers, campers, hunters and fishermen alike.

“Nobody ever fleshed out that information in that kind of detail. You couldn’t get lost in the mountains if you had that book,” said Jeff Lapides, a photographer and book designer from Sierra Madre who helped lay out Robinson’s later works.

Robinson would go on to write a companion book, “San Bernardino Mountain Trails,” another bestseller. Both had sold more than 70,000 copies by the 100th anniversary of the Angeles National Forest in 1993, according to the Sierra Club Angeles Chapter.

Robinson, a chapter member and tour guide since the 1950s, also wrote 70 articles for the organization’s “Hundred Peaks Section Newsletter” for editor Bob Cates, who later became a close friend.

Great Hiking Era

The essays became the core of another huge seller, “The San Gabriels,” first published in the 1970s and later expanded into a full volume in 1981 and again in 1991 and published by the Big Santa Anita Historical Society.

The hardbound book examined the history of the national forest from Soledad Canyon to Lytle Creek, and was crammed with stories and historical photos of Native American outposts, Spanish explorers and crafty innovators from the Greak Hiking Era of 1895 to 1938, such as Thaddeus Lowe, the builder of a mountain railway above the city of Pasadena.

The book includes the story of conservationist Abbott Kinney, a rancher known for building Venice with its canals, who helped bring about federal protection for the San Gabriels in 1892 after hunters slaughtered the grizzly bears and other animals to extinction and loggers felled trees for lumber, causing soil erosion and flooding.

Robinson later wrote “The San Bernardinos,” “Mines of the San Bernardinos,” “Mines of the San Gabriels,” “The Mount Wilson Story,” “Sierra Madre’s Old Mount Wilson Trail” and his latest, “Gateways to Southern California,” a 484-page examination of the passes traversed by explorers.

Robinson worked on “Gateways” for 14 years, said Lapides. It’s a tome that highlighted the discovery of treacherous cattle runs from Southern California to Northern California, a fact often left out of history books.

Sharing his knowledge

Riverside historian and Press-Enterprise columnist Steve Lech, author of “Along the Old Roads” on the formation of Riverside County, said Robinson provided him information on the San Jacinto Mountains.

Elizabeth Pomeroy, author of “John Muir in Southern California,” remembers meeting Robinson at a writers workshop in the 1990s where he volunteered to provide key information for her book.

“John was a very well-known and respected person. Yet he was down-to-earth, very approachable and always willing to help,” Lech said.

Pomeroy, who lives in Pasadena, added: “John Robinson has reached more people than any other person ever has about the San Gabriel Mountains.”

Bloggers liked him, too

Not only did Robinson influcence his generation of wilderness writers and hikers, but he was revered by a younger cohort of hiking bloggers, including Casey Schreiner of Los Angeles, creater of www.modernhiker.com.

At a 2014 authors’ gathering in Sierra Madre organized by Lapides, Robinson’s fans showed up en masse. The hall was filled with 300 people, mostly to talk to Robinson — including Schreiner, who bought “The San Gabriels” and had Robinson autograph it. The signed title page was posted on Modernhiker’s Facebook page the day after he died.

“Yeah, he was a total rock star at that event,” said Schreiner, 36, who in 2016 published his own trails book: “Day Hiking: Los Angeles.” In an interview Monday night, Schreiner said he added bits of history, along with trail-writing essentials such as directions, landmarks and distances, to his own book as an homage to Robinson.

“Yeah, I jammed a bit of history in there,” he said. “But he (Robinson) had amazing skills to drop in bits of knowledge from history and of the flora and fauna.”

Glen Owens, a Monrovia resident and president of the Big Santa Anita Historical Society, worked on several books with Robinson. Aside from noting his affable demeanor, Owens said Robinson’s folksy writing style was simple and direct, something he learned from his days as an elementary school teacher in Orange County.

“John wrote like he was sitting down and talking to you. The book would just flow. It was easy to follow and understand,” Owens said.

A mountain tribute?

Schreiner paid tribute by grabbing his copy of “Trails of the Angeles” and doing hike No. 1: A 6-mile roundtrip to Liebre Mountain, where the San Gabriels touch the Tehachapis near the Antelope Valley.

He read in the book the part about the black oaks blossoming in spring. Then he saw them right where Robinson said they would be.

“It was a nice way for me to commemorate him personally,” Schreiner said.

He suggested naming a mountain peak after Robinson, perhaps near the peak named for the late Will Thrall, a naturalist/author who preceded Robinson and was often quoted in his books. “Maybe we can call it Writers Ridge.”

Robinson is survived by three daughters, Cathy Robinson, Robyn Franz and Jeanne Robinson.
