This is some history of roads thru the Cajon Pass. Most in LA know this as the long hill climb in heavy traffic when heading to and from Vegas. For those not familiar with this itís on Interstate 15 between San Bernardino and Victorville
I donít know a lot about the use of the Cajon Pass by Native Americans, but they used and laid out tails long before others used it.
The Spanish trail ran thru the Cajon Pass. I seem to recall reading that there where a few routes, and it changed as needed. Like the Spanish Trail circa 1830, the Mojave Rd (Old Government or Bealeís Rd) and the Mormon Trail went though Cajon Pass.
The basic modern route stated with John Browns Toll road in the mid 1870ís. The first road was steep and prone to weather damage but can still be seen (pic 1) His 2nd road is still in use today as the FS road east of the Freeway down to 138. The section below 138 is the hiking trail down the lower end of Horse Thief Canyon. The Toll Road/ wagon/early car road would have crossed the 15 at the North bound truck scales (this little sub canyon has other names, but I donít recall them right now) into Lytle Creek where it basically got removed when route 66 was built thru the ĎBlue Cutí area.
IMO what was John Browns got less use once the RR was built, until the car became more common for travel. By that time it was no longer a Toll Road and was paved by the county where needed. Then Route 66, and later Interstate 15 became to road for the masses.
I took a class thru CSUSB which I enjoyed a lot. The instructor had lots of info, old pictures of places we went to, and they had permission to access closed and private areas.
Some of the places were; Willow Grove, A-frame eatery (pic 2), and Mathews Ranch. I recalled seeing the road to the tree area of the Mathews Ranch during past dirt road trips up Cajon Pass. It was also neat to see pictures and the area near Blue-Cut where the RR had done both river and rail re-routing. They showed us the Keenbrook Kiln (pic 3), which I had driven past before, but had not noticed.
If anyone wants info on the CSU class Iíll send it to ya, I highly recommend it to anyone with interest in the San Berdo county history.
