Lots of mountains have snow all the year round.
The mountain just has to be high enough that the average temperature is below 0°C most of the year, and the few days in summer which are above 0°C are not enough to melt all the snow which fell during the long winter.
Examples are the Himalayes, the Andes, the Alps etc.
a snow line is a line of snow on a mountain that stays there year round!

Around 5% of Alaska is covered with snow all year round, mostly in the highest mountain peaks and some areas in the far north.
Some examples of European mountains that are covered in snow year-round are the Alps in Switzerland and the Pyrenees in Andorra. These mountains have high elevations and cold temperatures, which contribute to their perpetual snow cover.
The high elevation of the mountain allows it to maintain cold temperatures despite its location near the equator. This results in snow accumulation that persists year-round at the peak.
Yes, there can still be snow on Mt. Rainier in July, particularly at higher elevations. The mountain's peak elevation of over 14,000 feet means that snow can persist year-round in some areas, even during the summer months.
One national park that has snow all year round is Mount Rainier National Park in Washington state. The park's high elevation and proximity to the Pacific Ocean contribute to its year-round snow cover.
I believe that Mt. Kilamajaro is in Africa somewhere, and given its height, being a mountain, it probably has snow all year round. Mount Kilimanjaro, in Tanzania, Africa, is Africa's highest mountain. Although it very close to the equator it is high enough that the temperature on the summit remains below freezing all year round. On top there is snow and small but permanent glacier of ice. Yep you can find it on Mount Kilimanjaro which is 19340 feet.
No, Mount Whitney is not snow covered year round. Snow typically covers the peak from late fall to early summer, with snowmelt occurring in the summer months. However, the exact timing and amount of snow can vary each year depending on weather conditions.
Yes, there are many glaciers on the mountain above about 8,000 feet where snow and ice don't melt. Hundreds of inches fall every year on Paradise Ranger station which is around 5500 feet, and it often doesn't completely melt until late June or July at that elevation. But it does all melt. You have to get above 7-8 thousand feet, depending on the year, to find snow that does not melt.

While Mount Fuji does have snow on its peak for a significant portion of the year, especially during the colder months, it does not have snow all year round. The snow typically remains on the summit from about October to around early June.
