Competition time. Welcome to the 39th Tioga pass Prognosticator. Spring opening 2025

[Southwest Dave]

Tioga pass Prognosticator. Spring 2025 opening competition.

Our 39th Tioga pass prognosticator offers you the opportunity to win a free tank of gas for your Road trip ride! It's free to enter and all you have to do is predict the correct date that the Tioga pass will open for the 2025 Road trip season. Tioga pass (aka CA120)crosses the Sierra Nevada in Yosemite NP at high altitude, and is one of the most dramatic drives for scenery anywhere in the world! It's a popular route for travellers who wish to traverse the mountains East to West, or vice versa, but come winter, snowfall and ice will close the road for the winter months, usually during November and December and remains closed until May or June and even into July, depending on the impact of winter. The plowing effort to clear the road of snow and ice, and debris from fallen trees and rock etc, starts in April and can take several weeks to clear. Not only is it a mammoth undertaking, there is also the risk of late winter storms slowing, or halting progress for the road crews!

Are you are up for the Challenge to become the new Tioga pass Prognosticator Champion and get a Tank of gas for your road trip ride?

All you have to do is follow the rules posted further down the page to predict the correct opening date for Spring 2025 and a tank of gas is yours! It doesn't matter how you get there, you can study data, use a crystal ball or throw a dart at a calendar, you just need the correct date. You can also add a bonus prize, enter a time and if you are within 60 minutes of the official opening time you will get an additional gift from RTA!

So far this season, it's been a pretty uneventful and dry winter season. January was drier and warmer than average and February has managed just one significant snowstorm that brought with it almost 4feet of new snow. Here's what it looks like form the High Sierra webcam this morning.
