Trail Markers

Prompt

Design a minimalistic icon representing trail markers, symbolizing outdoor adventure and navigation. The icon should feature a series of three stacked, vertical triangular shapes, resembling simplistic mountain peaks or directional markers. Each triangle should have different heights to create a sense of depth and variety, while maintaining a unified silhouette. Use clean lines and a rounded base for each triangle to convey a modern aesthetic. Incorporate a subtle gradient within the triangles to evoke the essence of natural landscapes, transitioning from green to earth tones. This icon should be easily recognizable and embody themes of exploration, suitable for outdoor apps or navigation tools that focus on trails and paths. Ensure that the overall composition is balanced and works well in both small and large sizes.
