Samuel

Solved by : Avantika(iamavu) and Starry-Lord

We have a youtube video https://www.youtube.com/watch?v=fDGVF1fK1cA. We can see a blurry video, with a beacon going on and off in the night, with what seems like cable-cars or planes in the distance. Short light and long lights seemed like morse code. Here’s the decoded morse.

WHWHWHGODWROUGHT

According to the link, Samuel Morse demonstrated the telegraph in 1844 with the sentence “what had God wrought”.

So we are looking for a beacon that sends the message in morse code, and I found this https://sculpturemagazine.art/mixed-messages-mark-bradfords-what-hath-god-wrought/

Avantika then found the location for this place on Google maps. https://www.google.com/maps/place/What+Hath+God+Wrought/@32.8752134,-117.2429636,17z/data=!3m1!4b1!4m5!3m4!1s0x80dc07e0d30e81a7:0x69087278617d6b1d!8m2!3d32.8752134!4d-117.2407749
