Is there still free land to homestead in the United States?

Hello there, I'm curious about a specific topic that's been piquing my interest lately. Is it still possible to find free land in the United States that one can homestead on? With the country's vast expanse and diverse geography, I'm wondering if there are any untapped areas where individuals can settle down, cultivate their own crops, and live off the land in a sustainable manner. Are there any legal considerations or restrictions that I should be aware of before embarking on such an endeavor? Thank you for your insights!
