"It's not the queen ... it's not the crown prince, but I will not make further statements until I know more," a harried Netherlands Prime Minister Mark Rutte said when questioned not long after the incident occurred.
Friso may have been buried in the snow mass for up to 20 minutes, according to the Associated Press, which cited local media. A tourist authority in the region said Friso was found through signals from an avalanche transceiver on his body, the AP said.
Friso was with a group skiing off piste in the Austrian Alps when the avalanche occurred, though he was the only one buried, news outlets reported.
Friso is married to Mabel Wisse Smit, and they have two young daughters.
Their marriage created a stir in 2004 as Friso gave up any claim to the throne to be married to the commoner and human rights activist.
The Dutch government refused to endorse the union, saying Wisse Smit had given misleading information about her relationship with a deceased gangster, according to the Guardian.
Then-Prime Minister Jan Peter Balkenende said in 2004 that the couple had given him "incomplete and incorrect information" during the standard prenuptial vetting process.
Wisse Smit and Friso later acknowledged misleading the government about the extent of her relationship with drug lord Klaas Bruinsma while she was in college in 1989.
The Dutch statement on the prince's condition said: "Her Majesty the Queen and Princess Mabel are with Prince Friso," according to the CBC.
