Despite having sufficient snow, a local ski mountain has decided to close in early march for the end of the ski season. what is the most likely reason to shut down in this situation

Most Ski resorts will try to extend the ski season as long as possible. This is because they are only going to earn money if they are open for business. In this case, the ski mountain is closing early in March instead of waiting until a more traditional time of year, probably late spring. While there may be a few reasons why the ski mountain might chose to close early even though there is sufficient snow this year, it is likely that this is a financial decision. If the ski mountain is not able to turn a profit, that is the most likely reason they will shut down early. If it is costing more to the keep the resort open then they can earn by staying open a few more weeks, then it would make sence to just shut down early.
