Critical Considerations

• Seasonal Closures: **Monitor Pass (CA-89), Ebbetts Pass (CA-4), Sonora Pass (CA-108) CLOSE Nov–May.** Carson Pass (CA-88) usually open year-round but chain control. **Check Caltrans QuickMap.**
• Altitude: US-395 crosses 7,000–8,000 ft passes; winter storms sudden.
• Fuel/Food: Long gaps (e.g., 100 mi between Ridgecrest and Bishop services). Fill in Barstow, Ridgecrest, Bishop.
• Time Zone: AZ (MST, no DST) → CA (PDT/PST) — gain/lose 1 hr depending on season.
