One forgotten yet significant tornado outbreak is the October 18, 1908 High Plains tornado outbreak. The Weather Bureau and Grazulis don't list any tornadoes from this outbreak, despite reliable newspaper reports of funnel clouds, debris being carried long distances, and significant tornado damage. At least three significant tornadoes occurred on this day, two of which were likely long-tracked tornado families.
Tornado #1 - Tucumcari NM
This intense tornado (family?) moved from near House to 12 miles NE of Tucumcari, devastating rural areas. Two people were killed on separate farms and several were injured. At least three farms were completely destroyed, including one that was swept away with "the only piece of timber of which the building (house) was constructed found in that vicinity after the storm being a piece of the door about a foot and a half long with the knob and lock." This was likely one of the most intense tornadoes in New Mexico's history and was possibly an F4.
Tornado #2 - Clayton NM
A complex long-lived family of possibly 3+ tornadoes begin just SE of Clayton, moving through the OK panhandle and ending NE of Campo CO. In Clayton itself, a large two-story brick courthouse lost its upper story with timber being carried 200-300 yards to the north, and numerous other buildings were damaged throughout town. Homes were destroyed both west and east of Clayton, likely by other tornadoes produced by different storms. 1 person died west of Clayton and 2 people died east of town. In Oklahoma, an entire farm was destroyed with one man dying on it, and a two-story building was destroyed at Mineral. In Colorado, the damage was much more minor with some windmills being destroyed.
Tornado #3 - Boise City OK
This brief but likely significant tornado completely destroyed at least four barns east of Boise City.
