A solar eclipse viewing party scheduled for the morning of Monday, April 8th at the Mount Wilson Observatory has been canceled, the Mount Wilson Institute says. In a Facebook post dated April 2, 2024, the institute writes “10 inches of new snow [has caused] road closures at the Observatory. Another snowstorm is forecasted for this Friday, April 5.” The powerful winter storm is expected to drop snow levels down the 2,000′ locally according to the National Weather Service office in Oxnard.
A total solar eclipse will be visible to parts of North America on Monday, April 8, 2024. While Southern California will miss totality by nearly 1,000 miles, a large portion of the sun is still going to be blocked by the moon. If viewing the eclipse from home, be sure to use solar glasses and never look directly at the sun.

Western Sycamores and White Alders are two of the most common tree species in Eaton Canyon, the former of which being considered a keystone species. Both of these tree species are also considered ‘relic’ species as they no longer exist across the Los Angeles Basin at the extent they did during the ice age 11,000 years ago. Today, their habitat is limited to the canyon floors where water is more regularly available. Both of these tree species require lots of water and cool summers to get through their infancy. With climate change making summers in Pasadena 7.2°F hotter than they were 100 years ago, there is no longer any such thing as a “cool summer” locally. Even worse, these higher temperatures mean increased rates of evaporation which dry up the creek faster than it normally would. Between 2006 and 2022, it is believed that there were no successful Western Sycamore or White Alder saplings at all below the first waterfall at Eaton Canyon.
All of that appears to have changed, however.

Since October 2022, weather stations around lower Eaton Canyon have reported between 73.06″ and 78.78″ of rainfall. This is currently the second wettest 24-month period on record, and there are still 6 months remaining in the water year. Records go back to 1909.
In spring 2023, something happened at Eaton Canyon that hadn’t been seen since 2019; creekside tree saplings. Winter 2023, despite its huge rains, lacked significant flash flooding in the canyon to destroy the wash. Thousands of Western Sycamore and White Alder tree sapling sprouted alongside the creek and began to grow. The worry, of course, was that summer 2023 was going to be too hot and dry for these saplings to survive just like every other summer of the past 2 decades had been. Indeed, July 2023 was record hot with more afternoons over 95°F than any other July on record. As a consequence, many of these young saplings began to perish especially in the lower wash where the creek had begun to dry up.

As Tropical Storm Hilary took aim at Southern California in late August 2023 and community members began sandbagging their homes, climatologists awed at the sheer rarity of such an event. The California Current is typically far too cold to support tropical entities making landfall in Los Angeles County, but in 2023, the perfect combination of ingredients made it happen. A midsummer deluge was certainly going to have an impact on Eaton Canyon, especially now that we had an entire new generation of tree saplings fighting for survival alongside Eaton Creek. The deluge came, no saplings died to flash flooding, and the creek was rejuvenated.
Eaton Canyon soaked at the height of summer 2023, precisely what these new trees needed
As of March 31, 2024, another winter of soaking rains without extensive flash flooding has kept these young tree saplings alive. Now, they have made it a full calendar year and have a much better chance of making it to adulthood. A repeat of 2023’s tropical storm Hilary is unlikely, but with the trees having developed some form of a root system, they will be better equipped to handle the drought and heat coming this summer.

On Saturday, March 23, 2024, yet another vehicle was broken into in the main parking lot at the Eaton Canyon Nature Center. The vehicle had its rear passenger window smashed in broad daylight by thieves looking to steal what was in the car’s backseat. Despite repeated attempts by the Los Angeles County Sheriff’s Department to stop the problem, the thieves remain at large.
Last summer on August 12th, eight vehicles in the overflow lot were targeted by thieves who made it in and out of the park in under 15 minutes. Most vehicles broken into were luxury cars. Break-ins have been reported at both the Midwick dirt parking pad and the Pinecrest Gate in the past 12 months. However, the overflow lot beside the Nature Center is where they occur most often.

Never leave anything in your vehicle when visiting Eaton Canyon, especially purses, credit cards, electronics, luggage, or backpacks. Hiding these items under your seat may not be sufficient to stop your vehicle from being targeted. If you aren’t taking it with you onto the trail, do not bring it to the canyon.
