In the women's skeleton, American Noelle Pikus-Pace claimed silver, Elizabeth Yarnold of Britain snagged the gold, and Russia's Elena Nikitina won the bronze.
Pikus-Pace's win puts America's overall medal count at 13, and in a tie with Norway for most medals. The Netherlands and Russia tie for second place with 12 medals, followed by Canada with 11 and Germany with 10.
Friday marked one of the warmest days at this year's games with the mercury hitting 3 degrees Celsius (55 degrees Fahrenheit) at the mountain-top venues.
Swiss skiers earned goal medals in both the men's classical-style 15-kilometer race and the men's super-combined slalom. The haul gave the Swiss five golds, only two behind Germany.
Dario Cologna won the 15-kilometer race to earn his second gold of the games. Cologna, who had ankle surgery in November, won the 30-kilometer skiathlon on Sunday.
Nineteen-year-old Yuzuru Hanyu of Japan overcame a pair of falls to become the first Asian man to win an Olympic title in men's figure skating.
Sandro Viletta stunned the favorites to win the super-combined. Two top Americans, defending champ Bodie Miller and world champion Ted Ligety, failed to win a medal.
A look at Friday's events:
FIGURE SKATING: Japan's Yuzuru Hanyu won the gold despite two falls during his free skate routine, largely because of the lead he built up with his record-setting short program. Canadian Patrick Chan, skating after Hanyu, won the silver despite three errors. World silver medalist Denis Ten of Kazakhstan took bronze.
CROSS-COUNTRY: In men's 15km classic, Sweden's Johan Olsson captured the silver, finishing 28.5 seconds behind Switzerland's Dario Cologna. Another Swede, Daniel Richardsson, took bronze.
ALPINE SKIING: In men's super combined combined slalom, Switzerland's Sandro Viletta took gold. Viletta finished the downhill and slalom runs in a combined time of 2 minutes, 45.20 seconds. Ivica Kostelic of Croatia earned the silver and Christof Innerhofer of Italy got bronze.
BIATHLON: Darya Domracheva of Belarus earned her second gold medal of the games by winning the women's 15-kilometer individual race. Domracheva, who also won the 12.5K pursuit three days ago, missed one target before finishing in 43 minutes, 19.6 seconds. Selina Gasparin of Switzerland finished 1:15.7 behind to take silver. Nadezhda Skardino of Belarus got the bronze.
FREESTYLE SKIING: Alla Tsuper of Belarus pulled off a stunning upset to win gold in women's aerials. Tsuper beat a field that included defending Olympic champion Lydia Lassila of Australia and two-time Olympic medalist Li Nina of China. The 34-year-old Tsuper had never finished higher than fifth in four previous Olympics. Xu Mengtao of China won silver while Lassila earned bronze.
SKELETON: Lizzy Yarnold of Britain won gold in women's skeleton, beating rival Noelle Pikus-Pace of the United States by a full second. It was Britain's first gold medal in Sochi. Winning the silver allowed Pikus-Pace to reach her goal of closing out her career with an Olympic medal. Elena Nikitina of Russia won the bronze.
CURLING: China and Britain won close games in the men's tournament to move into a three-way tie with Sweden atop the 10-country field. China beat Norway 7-5, while Britain topped Denmark 8-6. In the women's tournament, China beat South Korea, Britain defeated Japan, Russia beat Switzerland, and Denmark topped the U.S., all but eliminating the Americans from the playoffs.
ICE HOCKEY: Canada topped Austria 6-0 in the preliminary rounds of men's hockey. Also, Sweden beat Switzerland 1-0, the Czech Republic downed Latvia 4-2 and Finland defeated Norway 6-1.
