Poundcake Rock? Photo: Robert Sanchez/Axios John C. Frémont was one hungry fella. 🧭 Catch up quick: When the explorer (and future GOP presidential candidate) led an expedition in 1843, he and his team spotted a rocky monolith rising into the sky over present-day Castle Rock and thought: That looks like... a poundcake. Frémont wrote about it in his journal on July 9 that year. 🤤 To be fair,the expedition's food supplies were dwindling. Yes, but: Unlike the sugary treat, the name didn't stick.
