Jason Chandler

Jason Chandler is an inventor, explorer, and chairman of the Society of Explorers and Adventurers. He created the drilling tool that would mine into Big Thunder Mountain, and is a close friend of Barnabas T. Bullion.

Background
Jason Chandler was an inventor, who built a drill big and powerful enough to dig into the hardest of places. It attracted the attention of Barnabas T. Bullion, who bought it off of him to mine into Big Thunder Mountain. The two became close friends, going on expeditions together, exchanging letters, and visiting each other. However, Chandler was more cognizant of the troubles that would come with the mining, believing the stories about Big Thunder and urging his friend to stop before it was too late.

Chandler joined the Society of Explorers and Adventurers in the mid-1800s, as a secretary as early as 1851 and later as a chairman. He went on expeditions with other members, including one with Captain Brieux on the Hyperion ship to chart flying animals.

A letter is posted in the queue from Chandler to Barnabas T. Bullion's offices in Tumbleweed, reading the following:"Dear Barney,""Great Caesar’s Ghost, old chap, I haven’t heard from you since our little misadventure in El Dorado! I am indeed sorry to hear of the second disturbance within Big Thunder Mountain, but I did warn you that you were prospecting at your own peril when I sold you the drilling machine. I took the liberty of consulting Madame Zarkov at the Museum of the Weird, and it is her considered opinion that you should abandon the entire operation at once and find a less volatile site. I wish I had better news for you, old boy, but some forces simply are not to be trifled with.""On behalf of your compatriots of SEA, I do hope to see you around the club a bit more often!""Yours in Exploration and Adventure,""Jason Chandler""Founding Member The Society of Explorers and Adventurers"

Big Thunder Trail
A red carriage sits on the trail in Disneyland, near Big Thunder Mountain Railroad. A trunk sits at the top with a tag reading "Ship to Jason Chandler".

Soaring Fantastic Flight
Chandler, when he was a secretary, signed the document welcoming Camellia Falco to the Society of Explorers and Adventurers in 1851. It can be found in the attraction's queue.

The Tropical Hideaway
Chandler's ore from his 1882 expedition on the Elaho River in Canada can be found on a wall in this restaurant at Disneyland.

Discovery Bay
Chandler would have been the founder of this unbuilt Disneyland pavilion. After a bad experience at Big Thunder Mountain, he pursued science and established an outpost in California to help those matters. He funded research into strange and unusual sciences from people such as Professor Marvel and Captain Brieux. He would have been the star of the Discovery Bay Chronicles, as well, but only a pilot was produced.

Chandler is a miner in Rainbow Ridge, angry about the terrible working conditions and the disregard for miner safety. In retaliation, he started a gang of bandits alongside Onawa and Dolfo to steal the gold in Big Thunder Mountain and give it back to the townsfolk. Barnabas T. Bullion's daughter, Abigail, gets involved in the gang and they work together to change Rainbow Ridge for the better.

Chandler was only called by his last name until the final issue, where his first name was revealed to be Jason. It was done as an in-joke by the writers.
