Winter in Scotland conjures up images of the snow-topped mountains which attract visitors in their droves every year for walking, climbing and snowsports.
But enthusiasts say they have noticed a difference in recent years, with milder weather leading to less snow cover.
It has snowed this year, and is expected to do so again when Storm Ciara hits Scotland in the coming days, but lots of what has fallen has melted in thaws or been stripped away by strong winds.
Ben Dolphin, president of Ramblers Scotland and a winter walking enthusiast, said it wasn't unusual for conditions to vary from year to year on the hills.
