- dredmorbius 5y agoCorrect. It's the most recent possible occurence, or candidate occurrence. Not the most recent definite occurrence. We do know that it has not rained at that location for at least 130 years, at least sufficient to leave an ice-core trace. We do NOT know when it did rain most recently, previously, based on the information in the article.
