Longdale, Oklahoma: The Railroad Arrived in 1905 and the Town Became Real
Longdale is named for Lucious Walter Long, but the town really exists because of his wife Carrie. She donated their 160-acre homestead to a townsite company to make the development happen. Her name is not on the town, but her land is what the town stands on. The Longdale Ledger published its first issue on October 23, 1903, so the community had a newspaper before it had a railroad.
The Kansas City, Mexico and Orient Railway arrived on June 10, 1905. That is the date the town became an actual commercial center rather than just a cluster of homesteads. The railroad brought the grain market, the supplies, the ability to ship what this land produced. Before June 10, 1905, Longdale was a name on a map. After that date it was a working town.
Rural Blaine County farming community. Older homes, ranch property, the same mix of propane and aging central systems that you find throughout this part of Oklahoma. I service Longdale and the surrounding area. Call 405-375-4822.
Longdale, Oklahoma: Where Canton Lake Meets Blaine County Geo Country
Longdale is one of my favorite service calls in the whole territory, it’s near Canton Lake in Blaine County, about 50 miles northwest of Kingfisher, and the mix of properties is genuinely interesting. You’ve got lake-area homes and cabins that get heavy seasonal use and need reliable year-round comfort, working farms with older equipment that’s been coaxed along for too many years, and newer construction that sometimes has the opposite problem, brand-new equipment installed without a proper load calculation. All three of those situations have different answers, and I take the time to figure out which one I’m looking at before making any recommendation.
Blaine County is CKenergy electric co-op territory, which means Longdale homeowners may qualify for the $2,000-per-ton CKenergy geothermal rebate, the highest in my service area. The lake-area soil conditions and lot sizes around Longdale vary; some properties are excellent for horizontal loop geo, others may need vertical drilling depending on terrain. CKenergy also offers 6% financing for 4 to 7 years on energy-efficiency upgrades. I’ll walk your property, assess the soil and lot, calculate your load, and give you a written estimate, no obligation, no guessing. Call 405-375-4822 to schedule.
