While searching for secrets of the past, you find a scrap of paper that contains the following information:

01101110011100100110100001110000011010-
01011001000100110001001011110100001111
June 29, 1902

Because you’re great at OSINT, you trace this information back to a famous inscription. What is that inscription?
Flag: byuctf{inscription_with_underscores}
Note: the flag will not include the name or dates found in the inscription.

Instantly, we moved to Cyberchef for the binary conversion, and it resulted in nrhpidLKÐ. We thought it was garbage at first, until a teammate noticed “NRHP ID” within the string, which is related to the National Register of Historic Places. Since there’s a historic date also in the description, we can immediately conclude that this is the correct path to take. We isolated the last part and converted it into decimal instead - 80002319.

Following the trail for NRHP ID 80002319, we found this UpWiki Page About the “Jesse James Home Museum”, which is the location registered under this ID.

When we looked up “jesse james famous inscription”, we found a Smithsonian Magazine page that photographs Mr. James’ grave:

Removing the dates and names as the description specifies, the flag is byuctf{murdered_by_a_traitor_and_coward_whose_name_is_not_worthy_to_appear_here}.
