A Colorado ski area will be the first in the Rockies to open for the 2017-2018 season Friday, only days from its earliest opening day on record.

Arapahoe Basin, located about 45 miles west-southwest of Denver, announced Tuesday it will open for the season Friday at 9 a.m. 

The Black Mountain Express high-speed quad will be open, however, no beginner (green) runs will be available, according to the ski area's website

This opening day is eight days earlier than its 2016 opening date, and just four days later than its record earliest opening date of October 9, 2009.

As of Wednesday morning, A-Basin reported a mid-mountain snow depth of 18 inches, typically the threshold used for opening for the season. 

A cool, snowy stretch since late September has produced both natural snow, and has kept temperatures cool enough to allow snowmaking to build enough of a base for opening.

Nearby Winter Park, typically open by mid-November, picked up 19 inches of snowfall over a roughly two-week period since September 24, according to the National Weather Service.

"Our snowmaking efforts have gone very well with cold temperatures and high streamflows," wrote Alan Henceroth, chief operating officer for A-Basin, in an October 10 blog post

Just a few miles away, Loveland Ski Area has not yet announced an opening date, but was in the process of snowmaking. Loveland and Arapahoe Basin have a long-standing, friendly rivalry competing to be the first to open each season.

Assuming optimal weather for snowmaking or early-season snowfall, a number of ski areas around the country typically open for the season in November, particularly during Thanksgiving week in the Rockies, Sierra, Cascades, Upper Midwest, Appalachians, Adirondacks, Green and White Mountains, according to

We previously reported A-Basin would be the first ski area in the U.S. to open for the season, but that was incorrect. Oregon's Timberline Lodge, located near the top of Mt. Hood, opened for the season on October 8. Timberline is known for having the longest ski season in North America.

Half of the village of Big Sur, on the coast of central California, has lost its only access to the north following the demolition of the flood-damaged Pfeiffer Canyon Bridge along State Route 1 (also Rt. 1 or SR 1) on March 19. Although Rt. 1 to the south of Big Sur has reopened to traffic (after mud and rock slides were cleared) it is a long 70-mile journey along the windy but spectacular highway to Cambria, the next town of any significance where supplies can be had. CalTrans (California Department of Transportation) estimates it will take 6-9 months to rebuild a new bridge over the canyon.

Why the Arrest of a Science-Loving 14-year-old Matters

By now, many of you have heard or read about the arrest of Ahmed Mohamed, a 14-year-old high school student from Irving, Texas. Ahmed was arrested because school officials called the police after he showed one of his teachers his homemade clock. Mistaken for a bomb, Ahmed was taken into custody, interrogated, shamed, suspended (still on suspension today, Wednesday), and reprimanded. All of this after it has been found that the "device" he brought to school was indeed, a homemade clock.
