Montana acreage, unknown?

I have a section, in Richland County, Montana. The acreage is not stated. How would I find out how many acres are in that particular section?


I beleve a section is usually 640 acres. If you are referring to net mineral acres owned in a section, that information would be on record at the County Clerk's office in Richland County.

I believe each section contains 640 acres. I cound be wrong, but there was something on the internet that stated how many acres.
